Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note A—Summary of Significant Accounting Policies Nature of Operations. Robert Half Inc. (the “Company”) is a specialized talent solutions and business consulting firm, connecting highly skilled job seekers with rewarding opportunities at great companies. Robert Half ® offers contract talent solutions and permanent placement talent solutions for finance and accounting, technology, marketing and creative, legal, and administrative and customer support, and provides executive search services. Robert Half is also the parent company of Protiviti ® , a global consulting firm that delivers internal audit, risk, business, and technology consulting solutions. The Company operates in North America, South America, Europe, Asia, and Australia. The Company is a Delaware corporation. Basis of Presentation. The Consolidated Financial Statements (“Financial Statements”) of the Company are prepared in conformity with accounting principles generally accepted (“GAAP”) in the United States of America (“U.S.”) and the rules of the Securities and Exchange Commission (“SEC”). Certain reclassifications have been made to prior years’ consolidated financial statements to conform to the 2024 presentation Principles of Consolidation. The Financial Statements include the accounts of the Company and its subsidiaries, all of which are wholly owned. All intercompany balances and transactions have been eliminated in consolidation. Use of Estimates. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. As of December 31, 2024, such estimates include allowances for credit losses, variable consideration, workers’ compensation losses, accrued medical expenses, income and other taxes, and assumptions used in the Company’s goodwill impairment assessment and in the valuation of stock grants subject to market conditions. Actual results and outcomes may differ from management’s estimates and assumptions. Service Revenues. The Company derives its revenues from three segments: contract talent solutions, permanent placement talent solutions, and Protiviti. Revenues are recognized when promised goods or services are delivered to customers in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. See Note C— “ Revenue Recognition ” for further discussion of the revenue recognition accounting policy. Costs of Services. Direct costs of contract talent solutions consist of payroll, payroll taxes, and benefit costs for the Company’s engagement professionals, as well as reimbursable expenses. Direct costs of permanent placement talent solutions consist of reimbursable expenses. Protiviti direct costs of services include professional staff payroll, payroll taxes and benefit costs, as well as reimbursable expenses. Advertising Costs. The Company expenses all advertising costs as incurred. Advertising costs were $53.9 million, $54.8 million and $55.6 million for the years ended December 31, 2024, 2023, and 2022, respectively. (Income) Loss from Investments Held in Employee Deferred Compensation Trusts . Under the Company’s employee deferred compensation plans, employees direct the investment of their account balances, and the Company invests amounts held in the associated investment trusts consistent with these directions. As realized and unrealized investment gains and losses occur, the Company’s employee deferred compensation plan obligations change and adjustments are recorded in selling, general and administrative expenses or, in the case of Protiviti, costs of services. The value of the related investment trust assets also changes by an equal and offsetting amount, leaving no net cost to the Company, and therefore no effect on reported net income. The Company’s (income) loss from investments held in employee deferred compensation trusts consists of unrealized and realized gains and losses, and dividend income from trust investments and is presented separately on the Consolidated Statements of Operations. The following table presents the Company’s (income) loss from investments held in employee deferred compensation trusts (in thousands): Year Ended December 31, 2024 2023 2022 Dividend income $ (22,423) $ (15,049) $ (12,637) Realized and unrealized (gains) losses (71,656) (72,971) 98,776 (Income) loss from investments held in employee deferred compensation trusts (which is completely offset by related costs and expenses) $ (94,079) $ (88,020) $ 86,139 The following table presents the Company’s increase (decrease) in employee deferred compensation costs and expense related to changes in the fair value of trust assets for its nonqualified employee deferred compensation plans (in thousands): Year Ended December 31, 2024 2023 2022 Increase (decrease) in employee deferred compensation costs and expense related to changes in the fair value of trust assets $ 94,079 $ 88,020 $ (86,139) Comprehensive Income (Loss). Comprehensive income (loss) includes net income and certain other items that are recorded directly to stockholders’ equity. The Company’s only sources of other comprehensive income (loss) are foreign currency translation and foreign defined benefit plan adjustments. Cash and Cash Equivalents. The Company considers all highly liquid investments with a maturity at the date of purchase of three months or less as cash equivalents. This includes money market funds that meet the requirements to be treated as cash equivalents. However, money market funds held in investment trusts that are being used as investments to satisfy the Company’s obligations under its employee deferred compensation plans are treated as investments and are included in employee deferred compensation trust assets on the Consolidated Statements of Financial Position. Fair Value of Financial Instruments. Assets and liabilities recorded at fair value are measured and classified in accordance with a three-tier fair value hierarchy based on the observability of the inputs available in the market to measure fair value, summarized as follows: Level 1: observable inputs for identical assets or liabilities, such as quoted prices in active markets Level 2: inputs other than the quoted prices in active markets that are observable either directly or indirectly Level 3: unobservable inputs in which there is little or no market data, which requires management’s best estimates and assumptions that market participants would use in pricing the asset or liability The carrying value of cash and cash equivalents, net accounts receivable, and accounts payable and accrued expenses approximates fair value because of their short-term nature. The Company holds mutual funds and money market funds to satisfy its obligations under its employee deferred compensation plans which are carried at fair value based on quoted market prices in active markets for identical assets (Level 1). The following table summarizes the Company’s financial instruments by significant category and fair value measurement on a recurring basis (in thousands): Fair Value Measurements Using Balance at December 31, 2024 Quoted Prices Significant Other Observable Inputs Significant Unobservable Inputs Cash equivalents Money market funds $ 293,990 $ 293,990 — — Employee deferred compensation trust assets Money market funds $ 125,112 $ 125,112 — — Mutual funds - bonds 38,705 38,705 — — Mutual funds - stocks 401,751 401,751 — — Mutual funds - blend 107,672 107,672 — — Total employee deferred compensation trust assets $ 673,240 $ 673,240 — — Fair Value Measurements Using Balance at December 31, 2023 Quoted Prices Significant Other Observable Inputs Significant Unobservable Inputs Cash equivalents Money market funds $ 351,230 $ 351,230 — — Employee deferred compensation trust assets Money market funds $ 124,710 $ 124,710 — — Mutual funds - bonds 35,373 35,373 — — Mutual funds - stocks 316,764 316,764 — — Mutual funds - blend 94,199 94,199 — — Total employee deferred compensation trust assets $ 571,046 $ 571,046 — — Certain items, such as goodwill and other intangible assets, are recognized or disclosed at fair value on a non-recurring basis. The Company determines the fair value of these items using Level 3 inputs. There are inherent limitations when estimating the fair value of financial instruments, and the fair values reported are not necessarily indicative of the amounts that would be realized in current market transactions. Allowance for Credit Losses. The Company is exposed to credit losses resulting from the inability of its customers to make required payments. The Company establishes an allowance for these potential credit losses based on its review of customers’ credit profiles, historical loss statistics, prepayments, recoveries, age of customer receivable balances, current business conditions and macroeconomic trends. The Company considers risk characteristics of trade receivables based on asset type and geographical locations to evaluate trade receivables on a collective basis. The Company applies credit loss estimates to these pooled receivables to determine expected credit losses. The following table sets forth the activity in the allowance for credit losses from December 31, 2022, through December 31, 2024 (in thousands): Allowance for Credit Losses Balance as of December 31, 2022 $ 22,561 Charges to expense 8,752 Deductions (6,486) Other, including translation adjustments 362 Balance as of December 31, 2023 $ 25,189 Charges to expense 5,286 Deductions (8,009) Other, including translation adjustments (505) Balance as of December 31, 2024 $ 21,961 Property and Equipment . Property and equipment are recorded at cost. Depreciation is computed using the straight-line method over the following useful lives: Computer hardware 2 to 3 years Computer software 2 to 5 years Furniture and equipment 3 to 5 years Leasehold improvements Term of lease Internal-use Software. The Company develops and implements software for internal use to enhance the performance and capabilities of the operating technology infrastructure. Direct costs incurred for the development of internal-use software are capitalized from the time when the completion of the internal-use software is considered probable until the software is ready for use. All other preliminary and planning stage costs are expensed as incurred. Cloud computing implementation costs incurred in hosting arrangements are capitalized and reported as a component of other current assets and other noncurrent assets, while all other capitalized internal-use software development costs are reported as a component of computer software within property and equipment on the Consolidated Statements of Financial Position. Capitalized software costs are amortized using the straight-line method over the estimated useful life of the software, ranging from two Leases. The Company determines if a contractual arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, current operating lease liabilities, and noncurrent operating lease liabilities on the Consolidated Statements of Financial Position. The Company does not currently have finance leases. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the possession date (generally, this is the commencement date) of the lease based on the present value of lease payments over the lease term. The lease payments included in the present value are fixed lease payments and fixed management fees. The operating lease ROU assets include any payments made before the commencement date and exclude lease incentives. As most of the Company’s leases do not provide an implicit rate, the Company estimates its collateralized incremental borrowing rate, based on information available at the commencement date, in determining the present value of lease payments. The Company applies the portfolio approach in applying discount rates to its classes of leases. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company does not have any subleases. The Company does not currently have residual value guarantees or restrictive covenants in its leases. The Company has contracts with lease and non-lease components, which are accounted for on a combined basis. Goodwill and Intangible Assets . Goodwill and intangible assets primarily consist of the cost of acquired companies in excess of the fair market value of their net tangible assets at the date of acquisition. Identifiable intangible assets are amortized over their lives, typically ranging from two Income Taxes . The Company’s operations are subject to U.S. federal, state, local and foreign income taxes. In establishing its deferred income tax assets and liabilities and its provision for income taxes, the Company makes judgments and interpretations based on the enacted tax laws that are applicable to its operations in various jurisdictions. Deferred tax assets and liabilities are measured and recorded using current enacted tax rates, which the Company expects will apply to taxable income in the years in which those temporary differences are recovered or settled. The likelihood of a material change in the Company’s expected realization of its deferred tax assets is dependent on future taxable income and the effectiveness of its tax planning strategies in the various relevant jurisdictions. The Company also evaluates the need for valuation allowances to reduce the deferred tax assets to realizable amounts. Management evaluates all positive and negative evidence and uses judgment regarding past and future events, including operating results, to help determine when it is more likely than not that all or some portion of the deferred tax assets may not be realized. When appropriate, a valuation allowance is recorded against deferred tax assets to offset future tax benefits that may not be realized. Valuation allowances of $26.4 million and $25.8 million were recorded as of December 31, 2024, and 2023, respectively. The valuation allowances recorded related primarily to net operating losses in certain international operations. If such losses are ultimately utilized to offset future segment income, the Company will recognize a tax benefit up to the full amount of the valuation reserve. The Organization of Economic Cooperation and Development (“OECD”), an international association of many countries, has introduced a framework to impose a 15% global minimum corporate tax, referred to as Pillar Two, effective for tax years beginning in 2024. Currently, there are no laws enacted incorporating Pillar Two in the U.S., however, certain countries in which the Company operates have adopted, or are in the process of adopting legislation to implement Pillar Two. The OECD continues to release additional guidance and countries are implementing legislation with widespread adoption of the Global Anti-Base Erosion (“GloBE”) Model Rules for Pillar Two. The Company is continuing to evaluate the GloBE Model Rules for Pillar Two and related legislation; no material tax impacts are expected. Workers ’ Compensation . Except for states which require participation in state-operated insurance funds, the Company retains the economic burden for the first $0.5 million per occurrence in workers’ compensation claims. Workers’ compensation includes the ongoing medical and indemnity costs for claims filed, which may be paid over numerous years following the date of injury. Claims in excess of $0.5 million are insured. Workers’ compensation expense includes the insurance premiums for claims in excess of $0.5 million, claims administration fees charged by the Company’s workers’ compensation administrator, premiums paid to state-operated insurance funds, and an estimate for the Company’s liability for incurred but not reported (“IBNR”) claims and for the ongoing development of existing claims. The reserves for IBNR claims and for the ongoing development of existing claims in each reporting period include estimates. The Company has established reserves for workers’ compensation claims using loss development rates which are estimated using periodic third-party actuarial valuations based upon historical loss statistics, which include the Company’s historical frequency and severity of workers’ compensation claims, and an estimate of future cost trends. While management believes that its assumptions and estimates are appropriate, significant differences in actual experience or significant changes in assumptions may materially affect the Company’s future results. Accrued Medical Expenses. The Company offers several medical plans to its employees and retains the economic burden for the first $1.0 million per claimant per year in medical claims. Claims in excess of $1.0 million per year per claimant are insured. Medical expense includes the insurance premiums for claims in excess of $1.0 million, claims administration fees, prescription fees and reimbursements, and an estimate for the Company’s liability for IBNR claims and for the ongoing development of existing claims. Medical expenses are presented as a component of selling, general and administrative expenses, or in the case of Protiviti, costs of services in the Consolidated Statements of Operations. The reserves for IBNR claims and for the ongoing development of existing claims in each reporting period include estimates. The Company has established reserves for medical claims using rates which are estimated using periodic third-party actuarial valuations based upon historical loss statistics which include the Company’s historical claims data, and an estimate of future claim trends. While management believes that its assumptions and estimates are appropriate, significant differences in actual experience or significant changes in assumptions may materially affect the Company’s future results. Foreign Currency Translation. The reporting currency of the Company and its subsidiaries is the U.S. dollar. The functional currency of the Company’s international subsidiaries is their local currency. The results of operations of the Company’s international subsidiaries are translated at the monthly average exchange rates prevailing during the period. The financial position of the Company’s international subsidiaries is translated at the current exchange rates at the end of the period, and the related translation adjustments are recorded as a component of accumulated other comprehensive loss within Stockholders’ Equity. Gains and losses resulting from foreign currency transactions are included as a component of selling, general and administrative expenses in the Consolidated Statements of Operations and have not been material for all periods presented. Stock-based Compensation . Under various stock plans, officers, employees, and outside directors have received or may receive grants of restricted stock, stock units, stock appreciation rights or options to purchase common stock. The Company recognizes compensation expense equal to the grant-date fair value for all stock-based payment awards that are expected to vest. This expense is recorded on a straight-line basis over the requisite service period of the entire award. The Company determines the grant-date fair value of its restricted stock and stock unit awards using the fair market value of its stock on the grant date, unless the awards are subject to market conditions, in which case the Company utilizes an option-pricing model (i.e., Monte Carlo simulation model). The Monte Carlo simulation model utilizes multiple input variables to determine the stock-based compensation fair value. No stock appreciation rights have been granted under the Company’s existing stock plans. The Company has not granted any options to purchase common stock since 2006.

Revenue Recognition

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Note C—Revenue Recognition The Company derives its revenues from three segments: contract talent solutions, permanent placement talent solutions, and Protiviti. Revenues are recognized when promised goods or services are delivered to customers in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. Service revenues, as presented on the Consolidated Statements of Operations, represent services rendered to customers less variable consideration, such as sales adjustments and allowances. Reimbursements, including those related to travel and out-of-pocket expenses, are also included in service revenues, and equivalent amounts of reimbursable expenses are included in costs of services. Contract talent solutions revenues. Contract talent solutions revenues from contracts with customers are recognized in the amount to which the Company has a right to invoice when the services are rendered by the Company’s engagement professionals. The substantial majority of engagement professionals placed on assignment by the Company are the Company’s legal employees while they are working on assignments. The Company pays all related costs of employment, including workers’ compensation insurance, state and federal unemployment taxes, social security, and certain fringe benefits. The Company assumes the risk of acceptability of its employees to its customers. The Company records contract talent solutions revenue on a gross basis as a principal versus on a net basis as an agent in the presentation of revenues and expenses. The Company has concluded that gross reporting is appropriate because the Company (i) has the risk of identifying and hiring qualified employees, (ii) has the discretion to select the employees and establish their price and duties, and (iii) bears the risk for services that are not fully paid for by customers. Fees paid to time management or vendor management service providers selected by clients are recorded as a reduction of revenues, as the Company is not the primary obligor with respect to those services. Permanent placement talent solutions revenues. Permanent placement talent solutions revenues from contracts with customers are primarily recognized when employment candidates accept offers of permanent employment. The Company has a substantial history of estimating the financial impact of permanent placement candidates who do not remain with its clients through the 90-day guarantee period. These amounts are established based primarily on historical data and are recorded as liabilities. Fees to clients are generally calculated as a percentage of the new employee’s annual compensation. No fees for permanent placement talent solutions services are charged to employment candidates. Protiviti revenues. Protiviti’s consulting services are generally provided on a time-and-material basis, fixed-fee basis, or unit basis. Revenues earned under time-and-material arrangements and fixed-fee arrangements are recognized using a proportional performance method. Revenue is measured using cost incurred relative to total estimated cost for the engagement to measure progress towards satisfying the Company’s performance obligations. Cost incurred represents work performed and thereby best depicts the transfer of control to the customer. Protiviti’s consulting services generally contain one or more performance obligation(s) which are satisfied over a period of time. Revenues are recognized over time as the performance obligations are satisfied, because the services provided do not have any alternative use to the Company, and contracts generally include language giving the Company an enforceable right to payment for services provided to date. Unit-based revenues are recognized when the service has transferred to the customer. Revenue is recognized based on unit price multiplied by the number of units delivered and based on specific terms outlined in contracts. The Company periodically evaluates the need to provide for any losses on these projects, and losses are recognized when it is probable that a loss will be incurred. The following table presents the Company’s revenues disaggregated by functional specialization and segments (in thousands): Year Ended December 31, 2024 2023 2022 Contract talent solutions Finance and accounting $ 2,454,119 $ 2,811,093 $ 3,185,183 Administration and customer support 741,468 816,409 1,042,634 Technology 634,062 710,156 857,261 Elimination of intersegment revenues (a) (471,777) (442,326) (552,231) Total contract talent solutions 3,357,872 3,895,332 4,532,847 Permanent placement talent solutions 487,204 567,486 725,155 Protiviti 1,950,761 1,929,699 1,980,140 Total service revenues $ 5,795,837 $ 6,392,517 $ 7,238,142 (a) Service revenues for finance and accounting, administrative and customer support, and technology include intersegment revenues, which represent revenues from services provided to the Company’s Protiviti segment in connection with the Company’s blended business solutions. Intersegment revenues for each functional specialization are aggregated and then eliminated as a single line. Payment terms in the Company’s contracts vary by the type and location of the Company’s customer and the services offered. The term between invoicing and when payment is due is not significant. Contracts with multiple performance obligations are recognized as performance obligations are delivered, and contract value is allocated based on relative stand-alone selling values of the services and products in the arrangement. As of December 31, 2024, aggregate transaction price allocated to the performance obligations that were unsatisfied for contracts with an expected duration of greater than one year was $180.1 million. Of this amount, $169.7 million is expected to be recognized within the next 12 months. As of December 31, 2023, aggregate transaction price allocated to the performance obligations that were unsatisfied for contracts with an expected duration of greater than one year was $117.7 million. Contract liabilities are recorded when cash payments are received or due in advance of performance and are reflected in accounts payable and accrued expenses on the Consolidated Statements of Financial Position. The following table sets forth the activity in contract liabilities from December 31, 2022, through December 31, 2024 (in thousands): Contract Liabilities Balance as of December 31, 2022 $ 21,983 Payments in advance of satisfaction of performance obligations 47,719 Revenue recognized (44,862) Other, including translation adjustments (266) Balance as of December 31, 2023 $ 24,574 Payments in advance of satisfaction of performance obligations 44,138 Revenue recognized (44,086) Other, including translation adjustments (621) Balance as of December 31, 2024 $ 24,005

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note L—Commitments and Contingencies On March 23, 2015, Plaintiff Jessica Gentry, on her own behalf and on behalf of a putative class of allegedly similarly situated individuals, filed a complaint against the Company in the Superior Court of California, San Francisco County, which was subsequently amended on October 23, 2015. The complaint alleges that a putative class of current and former employees of the Company working in California since March 13, 2010, were denied compensation for the time they spent interviewing “for temporary and permanent employment opportunities” as well as performing activities related to the interview process. Gentry seeks recovery on her own behalf and on behalf of the putative class in an unspecified amount for this allegedly unpaid compensation. Gentry also seeks recovery of an unspecified amount for the alleged failure of the Company to provide her and the putative class with accurate wage statements. Gentry also seeks an unspecified amount of other damages, attorneys’ fees and statutory penalties, including penalties for allegedly not paying all wages due upon separation to former employees and statutory penalties on behalf of herself and other allegedly “aggrieved employees” as defined by California’s Labor Code Private Attorney General Act (“PAGA”). On January 4, 2016, the Court denied a motion by the Company to compel all of Gentry’s claims, except the PAGA claim, to individual arbitration. On March 8, 2024, the Court issued an order certifying: (1) a class of California-based temporary employees who attended at least one uncompensated interview with a third-party client at any time since March 13, 2010; (2) a subclass of class members who held a prior temporary job assignment before interviewing for a subsequent assignment; and (3) a subclass of class members who are no longer employed by the Company (i.e., a “waiting time penalties” subclass). At this stage of the litigation, it is not feasible to predict the outcome of or a range of loss, should a loss occur, from this proceeding and, accordingly, no amounts have been provided in the Company’s Financial Statements. The Company believes it has meritorious defenses to the allegations and the Company intends to continue to vigorously defend against the litigation. On April 6, 2018, Plaintiff Shari Dorff, on her own behalf and on behalf of a putative class of allegedly similarly situated individuals, filed a complaint against the Company in the Superior Court of California, County of Los Angeles. In addition to certain claims individual to Plaintiff Dorff, the complaint alleges that salaried recruiters based in California have been misclassified as exempt employees and seeks an unspecified amount for: unpaid wages resulting from such alleged misclassification; alleged failure to provide a reasonable opportunity to take meal periods and rest breaks; alleged failure to pay wages on a timely basis both during employment and upon separation; alleged failure to comply with California requirements regarding wage statements and record-keeping; and alleged improper denial of expense reimbursement. Plaintiff Dorff also seeks an unspecified amount of other damages, attorneys’ fees and penalties, including but not limited to statutory penalties on behalf of herself and other allegedly “aggrieved employees” as defined by PAGA. At this stage of the litigation, it is not feasible to predict the outcome of or a range of loss, should a loss occur, from this proceeding and, accordingly, no amounts have been provided in the Company’s Financial Statements. The Company believes it has meritorious defenses to the allegations and the Company intends to continue to vigorously defend against the litigation. The Company is involved in a number of other lawsuits arising in the ordinary course of business. While management does not expect any of these other matters to have a material adverse effect on the Company’s results of operations, financial position or cash flows, litigation is subject to certain inherent uncertainties. Legal costs associated with the resolution of claims, lawsuits and other contingencies are expensed as incurred. The Company has an uncommitted letter of credit facility (the “facility”) of up to $35.0 million, which is available to cover the issuance of debt support standby letters of credit. The Company had used $11.2 million and $14.3 million in debt support standby letters of credit as of December 31, 2024 and 2023, respectively, primarily to satisfy workers’ compensation insurer’s collateral requirements. There is a service fee of 1.1% to 1.2% on the used portion of the facility. The facility is subject to certain financial covenants and expires on August 31, 2025. The Company was in compliance with these covenants as of December 31, 2024. The Company intends to renew this facility prior to its August 31, 2025 expiration.

Share-Based Payment Arrangement [Abstract]
Stock Plans	Note N—Stock Plans Under various stock plans, officers, employees, and outside directors have received or may receive grants of restricted stock, stock units, stock appreciation rights or options to purchase common stock. Grants have been made at the discretion of the Committees of the Board of Directors. Grants generally vest either on a straight-line basis over four years or on a cliff basis over three years. Shares offered under the plan are authorized but unissued shares. Recipients of restricted stock do not pay any cash consideration to the Company for the shares and have the right to vote all shares subject to such grant. Restricted stock grants contain forfeitable rights to dividends. Dividends for these grants are accrued on the dividend payment dates but are not paid until the shares vest, and dividends accrued for shares that ultimately do not vest are forfeited. Recipients of stock units do not pay any cash consideration for the units, do not have the right to vote and do not receive dividends with respect to such units. During the year ended December 31, 2024, the Company granted performance shares to its executives in the form of restricted stock. The shares granted contain (1) a performance condition based on Return on Invested Capital (“ROIC”), and (2) a market condition based on Total Shareholder Return (“TSR”). The ROIC performance condition and the TSR market condition measure the Company’s performance against a peer group. Shares will be delivered at the end of a three-year vesting, TSR and ROIC performance period based on the Company’s actual performance compared to the peer group. The ROIC performance condition is calculated first and has a range of possible outcomes of zero percent (0%) to one-hundred fifty percent (150%). The TSR condition is considered a modifier of the ROIC performance condition. The range for the TSR condition is seventy-five percent (75%) to one-hundred twenty-five percent (125%). The result calculated by multiplying the ROIC percentage by the TSR percentage is used to calculate the actual number of shares earned. The fair value of this award was determined using a Monte Carlo simulation with the following weighted average assumptions: a historical volatility of 29.4%, a 0% dividend yield, and a risk-free interest rate of 4.5%. The historical volatility was based on the most recent 2.8-year period for the Company and the components of the peer group. The stock price movements have been modeled such that the dividends are incorporated in the returns of each company’s stock, therefore the Monte Carlo simulation reflects a 0% dividend yield for each stock. The use of a 0% dividend yield is mathematically equivalent to including the dividends in the calculation of TSR. The risk-free interest rate is equal to the yield, as of the valuation date, of the zero-coupon U.S. Treasury bill that is commensurate with the remaining performance period. Unrecognized compensation cost is expected to be recognized over the next four years. Total unrecognized compensation cost, net of estimated forfeitures, for restricted stock and stock units was $90.3 million, $93.7 million and $85.4 million for the years ended December 31, 2024, 2023 and 2022, respectively.

Segment Reporting [Abstract]
Business Segments	Note P—Business Segments The Company has three reportable segments: contract talent solutions, permanent placement talent solutions and Protiviti. Operating segments are defined as components of the Company for which separate financial information is evaluated regularly by the chief operating decision maker (“CODM”), a position currently held by the Company’s Chief Executive Officer, in deciding how to allocate resources and assess performance. The contract talent solutions reportable segment results from the aggregation of three operating segments with similar economic and qualitative characteristics: finance and accounting, administration and customer support and technology. The contract talent solutions and permanent placement talent solutions segments provide specialized engagement professionals and full-time personnel, respectively, for finance and accounting, technology, marketing and creative, legal, administrative and customer support roles. The Protiviti segment provides business and technology risk consulting and internal audit services. The CODM uses segment income to evaluate performance and allocate resources to each segment. Segment income excludes interest income, intangible assets amortization expense, income taxes and the impacts of deferred compensation (income) expense. The CODM considers variances between actual results and expectations as well as historical trends for segment income when making decisions about allocating capital and personnel resources to each segment. The accounting policies of the segments are set forth in Note A— “ Summary of Significant Accounting Policies. ” The following tables provide a reconciliation of service revenues and segment income by reportable segment to consolidated results (in thousands): Year Ended December 31, Contract Talent Solutions 2024 2023 2022 Service revenues (1) $ 3,357,872 $ 3,895,332 $ 4,532,847 Segment costs of services (2) 2,041,348 2,346,020 2,728,818 Compensation expenses (3) 884,121 934,024 973,341 Other (4) 301,885 322,473 338,407 Segment selling, general and administrative expenses 1,186,006 1,256,497 1,311,748 Segment income $ 130,518 $ 292,815 $ 492,281 Year Ended December 31, Permanent Placement Talent Solutions 2024 2023 2022 Service revenues (1) $ 487,204 $ 567,486 $ 725,155 Segment costs of services (2) 985 1,105 1,449 Compensation expenses (3) 359,205 405,747 506,006 Other (4) 80,962 85,630 90,078 Segment selling, general and administrative expenses 440,167 491,377 596,084 Segment income $ 46,052 $ 75,004 $ 127,622 Year Ended December 31, Protiviti 2024 2023 2022 Service revenues (1) $ 1,950,761 $ 1,929,699 $ 1,980,140 Segment costs of services (2) 1,487,511 1,454,127 1,427,675 Compensation expenses (3) 93,296 88,337 82,314 Other (4) 209,754 199,561 199,440 Segment selling, general and administrative expenses 303,050 287,898 281,754 Segment income $ 160,200 $ 187,674 $ 270,711 Year Ended December 31, Combined Segment 2024 2023 2022 Service revenues (1) $ 5,795,837 $ 6,392,517 $ 7,238,142 Costs of services (2) 3,529,844 3,801,252 4,157,942 Compensation expenses (3) 1,336,622 1,428,108 1,561,661 Other (4) 592,601 607,664 627,925 Selling, general and administrative expenses 1,929,223 2,035,772 2,189,586 Combined segment income 336,770 555,493 890,614 Amortization of intangible assets 1,217 2,883 1,667 Interest income, net (22,118) (23,973) (8,008) Income before income taxes $ 357,671 $ 576,583 $ 896,955 (1) Service revenues presented above are shown net of eliminations of intersegment revenues.

Cybersecurity Risk Management, Strategy, and Governance [Line Items]
Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	The Cybersecurity Incident Response Team (“CIRT”) and/or the Crisis Management Team (“CMT”) utilize a Cybersecurity Incident Response Plan (the “CIRP”) and the Playbook to: (1) prepare for and protect against Incidents; (2) detect and analyze Incidents; and (3) contain, eradicate and appropriately report on cybersecurity events. In the event of an Incident, the CIRP provides a framework to coordinate the response. The CIRP and Playbook also address escalation protocols to senior management with respect to disclosure determinations related to an Incident and provides for Executive Team briefings as appropriate. If the CIRT’s initial investigation of the facts of an Incident indicates the need for escalation for potential disclosure, the CMT will utilize the process in the Playbook and the Cyber Disclosure Procedure will be utilized. The Playbook provides understandable and flexible processes for analyzing and responding to Incidents. In the event of an Incident, the Playbook provides the CMT with predefined steps to follow to respond to, and escalate, cyber security incidents, as appropriate. The Cyber Disclosure Procedure establishes a flexible and context-dependent process for determining whether an Incident constitutes a material issue pursuant to the rules and regulations of the SEC. A committee of senior management personnel is established to assess potential Incidents. Standing members of the Cyber Disclosure Committee (“CDC”) include the President and Chief Executive Officer, Chief Financial Officer, General Counsel, Global Privacy Officer and Chief Technology Officer. In considering the materiality of an Incident the CDC may consider the nature, extent and potential magnitude of the risks to the Company related to the Incident, particularly as it may relate to any compromised information or the business and scope of Company operations. If the CDC determines the Board should be notified, a meeting will be called with the Executive Committee of the Board, the Audit Committee Chair, the Board’s cybersecurity expert or any combination or subset of the foregoing. EIS conducts cybersecurity evaluations, reviews and due diligence of (i) critical vendors periodically and (ii) all new vendors prior to onboarding. Vulnerabilities in third-party providers’ information security environments and software are monitored and managed through EIS’ vulnerability management program. This program aggregates findings from the vulnerability detection and secure configuration management tools within a dashboard, which allows EIS personnel to focus on high priority matters. EIS employs a variety of measures to prepare for and protect against, and detect, contain and eradicate cybersecurity incidents and threats. The preparatory and protective measures EIS has in place include, but are not limited to, password protection, multi-factor authentication, internal and external penetration testing, cybersecurity assessments, industry benchmarking, annual cybersecurity awareness trainings to employees, and social engineering awareness efforts. To detect and prevent Incidents, the cybersecurity program uses automated event-detection technology monitored by the cyber defense team, notifications from employees, vendors or service providers, and other tools. The Company has relationships with a number of third-party service providers to assist with Incident response and containment and remediation efforts, including a forensic investigation firm, insurance providers, auditors, consultants, assessors and various law firms. While the Company maintains a robust cybersecurity program, the techniques used to infiltrate information technology systems continue to evolve. Accordingly, the Company operates with, and plans for, the notion that it is impossible to prevent or detect all Incidents, that Incidents will occur, and that the Company will not always be able to detect threats in a timely manner or anticipate and implement adequate security measures. For additional information, see Item 1A. “Risks Related to the Company’s Information Technology, Cybersecurity and Data Protection.”

Principles of Consolidation	Principles of Consolidation. The Financial Statements include the accounts of the Company and its subsidiaries, all of which are wholly owned. All intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates.
Service Revenues and Costs of Services	Service Revenues. The Company derives its revenues from three segments: contract talent solutions, permanent placement talent solutions, and Protiviti. Revenues are recognized when promised goods or services are delivered to customers in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. See Note C— “ Revenue Recognition ” for further discussion of the revenue recognition accounting policy. Costs of Services. Direct costs of contract talent solutions consist of payroll, payroll taxes, and benefit costs for the Company’s engagement professionals, as well as reimbursable expenses. Direct costs of permanent placement talent solutions consist of reimbursable expenses. Protiviti direct costs of services include professional staff payroll, payroll taxes and benefit costs, as well as reimbursable expenses.
Advertising Costs	Advertising Costs.
(Income) Loss from Investments Held in Employee Deferred Compensation Trusts	(Income) Loss from Investments Held in Employee Deferred Compensation Trusts . Under the Company’s employee deferred compensation plans, employees direct the investment of their account balances, and the Company invests amounts held in the associated investment trusts consistent with these directions. As realized and unrealized investment gains and losses occur, the Company’s employee deferred compensation plan obligations change and adjustments are recorded in selling, general and administrative expenses or, in the case of Protiviti, costs of services. The value of the related investment trust assets also changes by an equal and offsetting amount, leaving no net cost to the Company, and therefore no effect on reported net income. The Company’s (income) loss from investments held in employee deferred compensation trusts consists of unrealized and realized gains and losses, and dividend income from trust investments and is presented separately on the Consolidated Statements of Operations.
Comprehensive Income (Loss)	Comprehensive Income (Loss). Comprehensive income (loss) includes net income and certain other items that are recorded directly to stockholders’ equity. The Company’s only sources of other comprehensive income (loss) are foreign currency translation and foreign defined benefit plan adjustments.
Cash and Cash Equivalents	Cash and Cash Equivalents. The Company considers all highly liquid investments with a maturity at the date of purchase of three months or less as cash equivalents. This includes money market funds that meet the requirements to be treated as cash equivalents. However, money market funds held in investment trusts that are being used as investments to satisfy the Company’s obligations under its employee deferred compensation plans are treated as investments and are included in employee deferred compensation trust assets on the Consolidated Statements of Financial Position.
Fair Value of Financial Instruments	Fair Value of Financial Instruments. Assets and liabilities recorded at fair value are measured and classified in accordance with a three-tier fair value hierarchy based on the observability of the inputs available in the market to measure fair value, summarized as follows: Level 1: observable inputs for identical assets or liabilities, such as quoted prices in active markets Level 2: inputs other than the quoted prices in active markets that are observable either directly or indirectly Level 3: unobservable inputs in which there is little or no market data, which requires management’s best estimates and assumptions that market participants would use in pricing the asset or liability The carrying value of cash and cash equivalents, net accounts receivable, and accounts payable and accrued expenses approximates fair value because of their short-term nature. The Company holds mutual funds and money market funds to satisfy its obligations under its employee deferred compensation plans which are carried at fair value based on quoted market prices in active markets for identical assets (Level 1).
Allowance for Credit Losses	Allowance for Credit Losses. The Company is exposed to credit losses resulting from the inability of its customers to make required payments. The Company establishes an allowance for these potential credit losses based on its review of customers’ credit profiles, historical loss statistics, prepayments, recoveries, age of customer receivable balances, current business conditions and macroeconomic trends. The Company considers risk characteristics of trade receivables based on asset type and geographical locations to evaluate trade receivables on a collective basis. The Company applies credit loss estimates to these pooled receivables to determine expected credit losses.
Property and Equipment	Property and Equipment . Property and equipment are recorded at cost. Depreciation is computed using the straight-line method over the following useful lives: Computer hardware 2 to 3 years Computer software 2 to 5 years Furniture and equipment 3 to 5 years Leasehold improvements Term of lease
Internal-use Software	Internal-use Software. two
Leases	Leases. The Company determines if a contractual arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (“ROU”) assets, current operating lease liabilities, and noncurrent operating lease liabilities on the Consolidated Statements of Financial Position. The Company does not currently have finance leases. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the possession date (generally, this is the commencement date) of the lease based on the present value of lease payments over the lease term. The lease payments included in the present value are fixed lease payments and fixed management fees. The operating lease ROU assets include any payments made before the commencement date and exclude lease incentives. As most of the Company’s leases do not provide an implicit rate, the Company estimates its collateralized incremental borrowing rate, based on information available at the commencement date, in determining the present value of lease payments. The Company applies the portfolio approach in applying discount rates to its classes of leases. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company does not have any subleases. The Company does not currently have residual value guarantees or restrictive covenants in its leases. The Company has contracts with lease and non-lease components, which are accounted for on a combined basis.
Goodwill and Intangible Assets	Goodwill and Intangible Assets . Goodwill and intangible assets primarily consist of the cost of acquired companies in excess of the fair market value of their net tangible assets at the date of acquisition. Identifiable intangible assets are amortized over their lives, typically ranging from two
Income Taxes	Income Taxes . The Company’s operations are subject to U.S. federal, state, local and foreign income taxes. In establishing its deferred income tax assets and liabilities and its provision for income taxes, the Company makes judgments and interpretations based on the enacted tax laws that are applicable to its operations in various jurisdictions. Deferred tax assets and liabilities are measured and recorded using current enacted tax rates, which the Company expects will apply to taxable income in the years in which those temporary differences are recovered or settled. The likelihood of a material change in the Company’s expected realization of its deferred tax assets is dependent on future taxable income and the effectiveness of its tax planning strategies in the various relevant jurisdictions. The Company also evaluates the need for valuation allowances to reduce the deferred tax assets to realizable amounts. Management evaluates all positive and negative evidence and uses judgment regarding past and future events, including operating results, to help determine when it is more likely than not that all or some portion of the deferred tax assets may not be realized. When appropriate, a valuation allowance is recorded against deferred tax assets to offset future tax benefits that may not be realized. Valuation allowances of $26.4 million and $25.8 million were recorded as of December 31, 2024, and 2023, respectively. The valuation allowances recorded related primarily to net operating losses in certain international operations. If such losses are ultimately utilized to offset future segment income, the Company will recognize a tax benefit up to the full amount of the valuation reserve.
Workers' Compensation	Workers ’ Compensation . Except for states which require participation in state-operated insurance funds, the Company retains the economic burden for the first $0.5 million per occurrence in workers’ compensation claims. Workers’ compensation includes the ongoing medical and indemnity costs for claims filed, which may be paid over numerous years following the date of injury. Claims in excess of $0.5 million are insured. Workers’ compensation expense includes the insurance premiums for claims in excess of $0.5 million, claims administration fees charged by the Company’s workers’ compensation administrator, premiums paid to state-operated insurance funds, and an estimate for the Company’s liability for incurred but not reported (“IBNR”) claims and for the ongoing development of existing claims. The reserves for IBNR claims and for the ongoing development of existing claims in each reporting period include estimates. The Company has established reserves for workers’ compensation claims using loss development rates which are estimated using periodic third-party actuarial valuations based upon historical loss statistics, which include the Company’s historical frequency and severity of workers’ compensation claims, and an estimate of future cost trends. While management believes that its assumptions and estimates are appropriate, significant differences in actual experience or significant changes in assumptions may materially affect the Company’s future results.
Accrued Medical Expenses	Accrued Medical Expenses. The Company offers several medical plans to its employees and retains the economic burden for the first $1.0 million per claimant per year in medical claims. Claims in excess of $1.0 million per year per claimant are insured. Medical expense includes the insurance premiums for claims in excess of $1.0 million, claims administration fees, prescription fees and reimbursements, and an estimate for the Company’s liability for IBNR claims and for the ongoing development of existing claims. Medical expenses are presented as a component of selling, general and administrative expenses, or in the case of Protiviti, costs of services in the Consolidated Statements of Operations. The reserves for IBNR claims and for the ongoing development of existing claims in each reporting period include estimates. The Company has established reserves for medical claims using rates which are estimated using periodic third-party actuarial valuations based upon historical loss statistics which include the Company’s historical claims data, and an estimate of future claim trends. While management believes that its assumptions and estimates are appropriate, significant differences in actual experience or significant changes in assumptions may materially affect the Company’s future results.
Foreign Currency Translation	Foreign Currency Translation. The reporting currency of the Company and its subsidiaries is the U.S. dollar. The functional currency of the Company’s international subsidiaries is their local currency. The results of operations of the Company’s international subsidiaries are translated at the monthly average exchange rates prevailing during the period. The financial position of the Company’s international subsidiaries is translated at the current exchange rates at the end of the period, and the related translation adjustments are recorded as a component of accumulated other comprehensive loss within Stockholders’ Equity. Gains and losses resulting from foreign currency transactions are included as a component of selling, general and administrative expenses in the Consolidated Statements of Operations and have not been material for all periods presented.
Stock-based Compensation	Stock-based Compensation . Under various stock plans, officers, employees, and outside directors have received or may receive grants of restricted stock, stock units, stock appreciation rights or options to purchase common stock. The Company recognizes compensation expense equal to the grant-date fair value for all stock-based payment awards that are expected to vest. This expense is recorded on a straight-line basis over the requisite service period of the entire award. The Company determines the grant-date fair value of its restricted stock and stock unit awards using the fair market value of its stock on the grant date, unless the awards are subject to market conditions, in which case the Company utilizes an option-pricing model (i.e., Monte Carlo simulation model). The Monte Carlo simulation model utilizes multiple input variables to determine the stock-based compensation fair value.
Recently Adopted Accounting Pronouncements/Recently Issued Accounting Pronouncements Not Yet Adopted	Recently Adopted Accounting Pronouncements Segment Reporting. In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The amendments in the ASU are intended to improve reportable segment disclosure requirements primarily through enhanced disclosures about significant segment expenses. This ASU is effective for public filers for fiscal periods beginning after December 15, 2023, and interim periods beginning after December 15, 2024, however early adoption is permitted. The Company adopted the new guidance for the fiscal year ended December 31, 2024, resulting in additional disclosures to the Company’s segment financial information footnote. The impact of the adoption was not material to the Company’s consolidated financial statements. Recently Issued Accounting Pronouncements Not Yet Adopted Income Tax Disclosures . In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. Under this ASU, public filers must disclose annually (1) specific categories in the rate reconciliation, and (2) provide additional information for reconciling items that meet a quantitative threshold, if the effect of those reconciling items is equal to or greater than five percent of the amount computed by multiplying pretax income by the applicable statutory income tax rate. The new guidance is effective for public filers for annual periods beginning after December 15, 2024. Early adoption is permitted. The Company is currently evaluating the impact of the new guidance on its consolidated financial statements and related disclosures. Income Statement Disclosures. In November 2024, the FASB issued ASU 2024-03, Income Statement, Reporting Comprehensive Income, Expense Disaggregation Disclosures (Subtopic 220-40). This ASU requires disclosure of disaggregated information about specific categories underlying certain income statement expense line items in the notes to the financial statements. This guidance is effective for public filers for annual periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted.
