Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION The condensed consolidated balance sheets and related condensed consolidated statements of comprehensive income and cash flows contained in this Quarterly Report on Form 10-Q (this “Quarterly Report”), which are unaudited, include the accounts of AMN Healthcare Services, Inc. and its wholly-owned subsidiaries (collectively, the “Company”). All significant intercompany balances and transactions have been eliminated in consolidation. In the opinion of management, all entries necessary for a fair presentation of such unaudited condensed consolidated financial statements have been included. These entries consisted of all normal recurring items. The results of operations for the interim period are not necessarily indicative of the results to be expected for any other interim period or for the entire fiscal year or for any future period. The unaudited condensed consolidated financial statements do not include all information and notes necessary for a complete presentation of financial position, results of operations and cash flows in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”). Please refer to the Company’s audited consolidated financial statements and the related notes for the fiscal year ended December 31, 2019, contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2019, filed with the Securities and Exchange Commission on February 25, 2020 (“2019 Annual Report”). The preparation of financial statements in conformity with U.S. GAAP requires management to make a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenue and expenses during the reporting periods. On an ongoing basis, the Company evaluates its estimates, including those related to intangible assets purchased in a business combination, asset impairments, accruals for self-insurance, compensation and related benefits, accounts receivable, contingencies and litigation, earn-out liabilities, and income taxes. Actual results could differ from those estimates under different assumptions or conditions. Coronavirus Pandemic On March 11, 2020, the World Health Organization declared the outbreak of a novel strain of coronavirus, also known as COVID-19, a global pandemic. Due to the pandemic, there has been uncertainty and disruption in the global economy and significant volatility of financial markets. The Company is closely monitoring the impact of the pandemic, which continues to evolve, and its effects and risks on our operations, liquidity, financial condition and financial results for the full year 2020 and, possibly, beyond. The estimates used for, but not limited to, determining the collectability of accounts receivable, fair value of long-lived assets, and goodwill could be impacted by the pandemic. While the full impact of COVID-19, including the duration and severity of the pandemic, remains unknown, the Company has made appropriate estimates based on the facts and circumstances available as of the reporting date. Specifically, the Company continues to monitor the impacts of the pandemic on its customers’ liquidity and capital resources and, therefore, the Company’s ability to collect, or the timeliness of collection of accounts receivable. The impact of COVID-19 did not have a material effect on the Company’s estimates as of June 30, 2020. These estimates may change as new events occur and additional information is obtained. See additional information below regarding the allowance for credit losses for accounts receivable. Recently Adopted Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2016-13, “Measurement of Credit Losses on Financial Instruments.” The FASB also issued a series of other ASUs, which update ASU 2016-13 (collectively, the “credit loss standard”). This new standard introduces new accounting models for determining and recognizing credit losses on certain financial instruments based on an estimate of current expected credit losses. The Company adopted this standard effective January 1, 2020 using the modified retrospective transition method. The Company recognized the cumulative effect of adopting this guidance as an adjustment to the opening balance of retained earnings of $1,154, net of tax, primarily related to its allowance for credit losses for accounts receivable. Prior period amounts are not retrospectively adjusted. The impact of the adoption of the new standard was not material to the Company’s condensed consolidated financial statements for the three and six months ended June 30, 2020. The Company expects the impact to be immaterial on an ongoing basis. See additional information below regarding the allowance for credit losses for accounts receivable. In January 2017, the FASB issued ASU 2017-04, “Simplifying the Test for Goodwill Impairment.” The standard simplifies the subsequent measurement of goodwill by removing the requirement to perform a hypothetical purchase price allocation to compute the implied fair value of goodwill to measure impairment. Instead, any goodwill impairment will equal the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. Further, the guidance eliminates the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. The Company adopted this standard effective January 1, 2020 and the adoption did not have a material effect on the Company’s consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, “Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement.” The standard modifies the current disclosure requirements on fair value measurements. The Company adopted this standard effective January 1, 2020. Refer to information regarding fair value measurements in Note (7), “Fair Value Measurement.” Cash, cash equivalents and restricted cash The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents.

Business Combinations [Abstract]
ACQUISITIONS	ACQUISITIONS As set forth below, the Company completed four acquisitions from January 1, 2019 through June 30, 2020. The Company accounted for each acquisition using the acquisition method of accounting. Accordingly, it recorded the tangible and intangible assets acquired and liabilities assumed at their estimated fair values as of the applicable date of acquisition. Since the applicable date of acquisition, the Company has revised the allocation of the purchase price to the tangible and intangible assets acquired and liabilities assumed based on analysis of information that has been made available through June 30, 2020. The allocations will continue to be updated through the measurement period, if necessary. The Company recognizes acquisition-related costs in selling, general and administrative expenses in the consolidated statements of comprehensive income. Stratus Video Acquisition On February 14, 2020, the Company completed its acquisition of Stratus Video, a remote video interpreting company that provides healthcare interpretation via remote video, over the phone, and onsite in-person, all supported by proprietary technology platforms. The initial purchase price of $485,568 consisted entirely of cash consideration paid upon acquisition. The acquisition was funded primarily through (1) borrowings under the Company’s $400,000 secured revolving credit facility (the “Senior Credit Facility”), provided for under a credit agreement (the “New Credit Agreement”), and (2) the Second Amendment (as defined in Note (6) below) to the New Credit Agreement, which provided $250,000 of additional available borrowings to the Company. The New Credit Agreement and the Second Amendment are more fully described in Note (6), “Notes Payable and Credit Agreement.” The results of Stratus Video have been included in the Company’s technology and workforce solutions segment since the date of acquisition. During the second quarter of 2020, an additional $99 of cash consideration was paid to the selling shareholders for the final working capital settlement.

Revenue Recognition

Revenue from Contract with Customer [Abstract]
REVENUE RECOGNITION	REVENUE RECOGNITION Revenue primarily consists of fees earned from the temporary staffing and permanent placement of healthcare professionals, executives, and leaders (clinical and operational). The Company also generates revenue from its software as a service (“SaaS”)-based technologies, including vendor management systems and scheduling software, and outsourced workforce services, including language interpretation and recruitment process outsourcing. Revenue is recognized when control of these services is transferred to the customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those services. Revenue from temporary staffing services is recognized as the services are rendered by clinical and non-clinical healthcare professionals. Under the Company’s managed services program (“MSP”) arrangements, the Company manages all or a part of a customer’s supplemental workforce needs utilizing its own network of healthcare professionals along with those of third-party subcontractors. Revenue and the related direct costs under MSP arrangements are recorded in accordance with the accounting guidance on reporting revenue gross as a principal versus net as an agent. When the Company uses subcontractors and acts as an agent, revenue is recorded net of the related subcontractor’s expense. Revenue from permanent placement and outsourced workforce services is recognized as the services are rendered. Depending on the arrangement, the Company’s SaaS-based revenue is recognized either as the services are rendered or ratably over the applicable arrangement’s service period. The Company’s customers are primarily billed as services are rendered. Any fees billed in advance of being earned are recorded as deferred revenue. While payment terms vary by the type of customer and the services rendered, the term between invoicing and when payment is due is not significant. During the six months ended June 30, 2020 and 2019, previously deferred revenue recognized as revenue was $10,371 and $8,641, respectively. The Company has elected to apply the following practical expedients and optional exemptions related to contract costs and revenue recognition: • Recognize incremental costs of obtaining a contract with amortization periods of one year or less as expense when incurred. These costs are recorded within selling, general and administrative expenses. • Recognize revenue in the amount of consideration to which the Company has a right to invoice the customer if that amount corresponds directly with the value to the customer of the Company’s services completed to date. • Exemptions from disclosing the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less, (ii) contracts for which revenue is recognized in the amount of consideration to which the Company has a right to invoice for services performed and (iii) contracts for which variable consideration is allocated entirely to a wholly unsatisfied performance obligation or to a wholly unsatisfied promise to transfer a distinct service that forms part of a single performance obligation. See Note (5), “Segment Information” for additional information.

Segment Reporting [Abstract]
SEGMENT INFORMATION	SEGMENT INFORMATION The Company’s operating segments are identified in the same manner as they are reported internally and used by the Company’s chief operating decision maker for the purpose of evaluating performance and allocating resources. Effective March 8, 2020, the Company modified its reportable segments. The Company previously utilized three reportable segments, which it identified as follows: (1) nurse and allied solutions, (2) locum tenens solutions, and (3) other workforce solutions. In light of the Company’s recent acquisitions and organizational changes to better align its organizational structure with its strategy and operations, the Company’s management reorganized its reportable segments to better reflect how the business is evaluated by the chief operating decision maker. Beginning in the first quarter of 2020, the Company has disclosed the following three reportable segments: (1) nurse and allied solutions, (2) physician and leadership solutions, and (3) technology and workforce solutions. The nurse and allied solutions segment includes the Company’s travel nurse staffing, rapid response nurse staffing and labor disruption, allied staffing, local staffing, and revenue cycle solutions businesses. The physician and leadership solutions segment includes the Company’s locum tenens staffing, healthcare interim leadership staffing, executive search, and physician permanent placement businesses. The technology and workforce solutions segment includes the Company’s language interpretation services, vendor management systems, workforce optimization, recruitment process outsourcing, credentialing, and flex pool management businesses. The Company’s chief operating decision maker relies on internal management reporting processes that provide revenue and operating income by reportable segment for making financial decisions and allocating resources. Segment operating income represents income before income taxes plus depreciation, amortization of intangible assets, share-based compensation, interest expense, net, and other, and unallocated corporate overhead. The Company’s management does not evaluate, manage or measure performance of segments using asset information; accordingly, asset information by segment is not prepared or disclosed. The following table, which includes reclassified prior period data to conform to the new segment reporting structure, provides a reconciliation of revenue and operating income by reportable segment to consolidated results and was derived from each segment’s internal financial information as used for corporate management purposes: Three Months Ended June 30, Six Months Ended June 30, 2020 2019 2020 2019 Revenue Nurse and allied solutions $ 444,464 $ 367,994 $ 868,810 $ 741,466 Physician and leadership solutions 108,622 142,449 246,464 279,526 Technology and workforce solutions 55,265 24,734 95,538 46,626 $ 608,351 $ 535,177 $ 1,210,812 $ 1,067,618 Segment operating income Nurse and allied solutions $ 61,175 $ 52,752 $ 120,783 $ 106,308 Physician and leadership solutions 15,325 18,861 29,894 34,733 Technology and workforce solutions 21,839 11,336 37,134 21,719 98,339 82,949 187,811 162,760 Unallocated corporate overhead 31,165 21,373 59,733 39,236 Depreciation and amortization 22,071 12,718 42,160 24,428 Depreciation (included in cost of revenue) 355 — 500 — Share-based compensation 6,347 3,702 11,274 8,888 Interest expense, net, and other 11,443 6,065 22,497 11,738 Income before income taxes $ 26,958 $ 39,091 $ 51,647 $ 78,470 The following tables present the Company’s revenue disaggregated by service type.

The Company performed a goodwill impairment test at the reporting unit level both immediately before and after the reorganization. The Company determined the fair values of its reporting units using a combination of the income approach (using discounted future cash flows) and the market valuation approach. Based on the results of this testing, the Company determined that the fair values of its reporting units were each greater than their respective carrying values both before and after the reorganization. Therefore, there was no impairment loss recognized during the six months ended June 30, 2020. The following table summarizes the activity related to the carrying value of goodwill by reportable segment: Nurse and Allied Solutions Physician and Leadership Solutions Technology and Workforce Solutions Total Balance, January 1, 2020 $ 344,316 $ 163,348 $ 87,887 $ 595,551 Goodwill adjustment for Advanced acquisition 29 — — 29 Goodwill adjustment for b4health acquisition — — (66) (66) Goodwill from Stratus Video acquisition — — 274,560 274,560 Reallocation due to change in segments (14,600) 297 14,303 — Balance, June 30, 2020 $ 329,745 $ 163,645 $ 376,684 $ 870,074 Accumulated impairment loss as of December 31, 2019 and June 30, 2020 $ 154,444 $ 60,495 $ — $ 214,939

Debt Disclosure [Abstract]
NOTES PAYABLE AND CREDIT AGREEMENT	NOTES PAYABLE AND CREDIT AGREEMENT On February 9, 2018, the Company entered into the New Credit Agreement with several lenders to provide for the $400,000 Senior Credit Facility to replace its then-existing credit facilities. The Senior Credit Facility includes a $50,000 sublimit for the issuance of letters of credit and a $50,000 sublimit for swingline loans. On June 14, 2019, the Company entered into the first amendment to the New Credit Agreement (the “First Amendment”) to provide for, among other things, a $150,000 secured term loan credit facility (the “Term Loan”). The Company used the proceeds from the Term Loan, together with a drawdown of a portion of the Senior Credit Facility, to complete its acquisition of Advanced, as more fully described in Note (2), “Acquisitions.” The Company fully repaid all amounts under the Term Loan in 2019. On February 14, 2020, the Company entered into the second amendment to the New Credit Agreement (the “Second Amendment”) to provide for, among other things, a $250,000 secured term loan credit facility (the “Additional Term Loan”). The Second Amendment (together with the New Credit Agreement and the First Amendment, collectively, the “Amended Credit Agreement”) extended the maturity date of the Senior Credit Facility to be coterminous with the Additional Term Loan. The obligations of the Company under the Amended Credit Agreement are secured by substantially all of the assets of the Company. The Company used the proceeds from the Additional Term Loan, together with a drawdown of a portion of the Senior Credit Facility, to complete its acquisition of Stratus Video as more fully described in Note (2), “Acquisitions.” Borrowings under the Senior Credit Facility and the Additional Term Loan (together, the “Credit Facilities”) bear interest at floating rates, at the Company’s option, based upon either LIBOR plus a spread of 1.00% to 1.75% or a base rate plus a spread of 0.00% to 0.75%. The applicable spread is determined quarterly based upon the Company’s consolidated net leverage ratio (as calculated per the Amended Credit Agreement). The Additional Term Loan is subject to amortization of principal of 2.50% per year for the first year of the term and 5.00% per year thereafter, payable in equal quarterly installments. The Senior Credit Facility is available for working capital, capital expenditures, permitted acquisitions and general corporate purposes. The maturity date of the Credit Facilities is February 14, 2025. In connection with the Second Amendment, the Company incurred $3,899 in fees paid to lenders and other third parties, which were capitalized during the three months ended March 31, 2020 and are amortized to interest expense over the term of the Credit Facilities. In addition, $1,681 of unamortized financing fees incurred in connection with obtaining the New Credit Agreement and First Amendment will continue to be amortized to interest expense over the term of the Credit Facilities.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENT	FAIR VALUE MEASUREMENT The Company’s valuation techniques and inputs used to measure fair value and the definition of the three levels (Level 1, Level 2, and Level 3) of the fair value hierarchy are disclosed in Part II, Item 8, “Financial Statements and Supplementary Data—Notes to Consolidated Financial Statements—Note 3—Fair Value Measurement” of the 2019 Annual Report. The Company has not changed the valuation techniques or inputs it uses for its fair value measurement during the three and six months ended June 30, 2020. Assets and Liabilities Measured on a Recurring Basis The Company’s restricted cash equivalents that serve as collateral for the Company’s outstanding letters of credit typically consist of money market funds that are measured at fair value based on quoted prices, which are Level 1 inputs. The Company has a deferred compensation plan for certain executives and key employees, which is composed of deferred compensation and all related income and losses attributable thereto. The Company’s obligation under its deferred compensation plan is measured at fair value based on quoted market prices of the participants’ elected investments, which are Level 1 inputs. The Company’s restricted cash equivalents and investments that serve as collateral for the Company’s captive insurance company primarily consist of commercial paper that is measured at observable market prices for identical securities that are traded in less active markets, which are Level 2 inputs. Of the $52,752 commercial paper issued and outstanding as of June 30, 2020, $18,680 had original maturities greater than three months, which were considered available-for-sale securities. As of December 31, 2019, the Company had $59,243 commercial paper issued and outstanding, of which $9,586 had original maturities greater than three months and were considered available-for-sale securities. The Company’s contingent consideration liabilities are measured at fair value using a probability-weighted discounted cash flow analysis or a simulation-based methodology for the acquired companies, which are Level 3 inputs. The Company recognizes changes to the fair value of its contingent consideration liabilities in selling, general and administrative expenses in the condensed consolidated statements of comprehensive income. The following tables present information about the above-referenced assets and liabilities and indicate the fair value hierarchy of the valuation techniques utilized to determine such fair value: Fair Value Measurements as of June 30, 2020 Total Quoted Prices in Significant Other Observable Inputs Significant Unobservable Inputs Money market funds $ 2,519 $ 2,519 $ — $ — Deferred compensation (84,338) (84,338) — — Commercial paper 52,752 — 52,752 — Acquisition contingent consideration liabilities (8,100) — — (8,100) Fair Value Measurements as of December 31, 2019 Total Quoted Prices in Significant Other Observable Inputs Significant Unobservable Inputs Money market funds $ 2,508 $ 2,508 $ — $ — Deferred compensation (81,064) (81,064) — — Commercial paper 59,243 — 59,243 — Acquisition contingent consideration liabilities (23,100) — — (23,100) Level 3 Information The following table sets forth a reconciliation of changes in the fair value of contingent consideration liabilities classified as Level 3 in the fair value hierarchy: 2020 2019 Balance as of April 1, $ (3,300) $ (8,500) Settlement of PDA and LFT contingent consideration liability for year ended December 31, 2018 — 7,000 Contingent consideration liability from Advanced acquisition on June 14, 2019 — (10,622) Change in fair value of contingent consideration liability from Silversheet acquisition — 1,458 Change in fair value of contingent consideration liability from b4health acquisition (4,800) — Balance as of June 30, $ (8,100) $ (10,664) 2020 2019 Balance as of January 1, $ (23,100) $ (7,700) Settlement of PDA and LFT contingent consideration liability for year ended December 31, 2018 — 7,000 Settlement of Advanced contingent consideration liability for year ended December 31, 2019 20,000 — Contingent consideration liability from Silversheet acquisition on January 30, 2019 — (1,500) Contingent consideration liability from Advanced acquisition on June 14, 2019 — (10,622) Change in fair value of contingent consideration liability from MedPartners acquisition — 700 Change in fair value of contingent consideration liability from Silversheet acquisition — 1,458 Change in fair value of contingent consideration liability from b4health acquisition (5,000) — Balance as of June 30, $ (8,100) $ (10,664) The fair value measurements of contingent consideration liabilities classified as Level 3 in the fair value hierarchy include the following significant unobservable inputs: As of June 30, 2020 As of December 31, 2019 Volatility 75.0% 50.0% Discount rate 13.1% 16.5% Risk-free rate 0.2% 1.5% Cost of debt 6.3% 5.3% Assets Measured on a Non-Recurring Basis The Company applies fair value techniques on a non-recurring basis associated with valuing potential impairment losses related to its goodwill, indefinite-lived intangible assets, long-lived assets, and equity investments. The Company evaluates goodwill and indefinite-lived intangible assets annually for impairment and whenever circumstances occur indicating that goodwill might be impaired. The Company determines the fair value of its reporting units based on a combination of inputs, including the market capitalization of the Company, as well as Level 3 inputs such as discounted cash flows, which are not observable from the market, directly or indirectly. The Company determines the fair value of its indefinite-lived intangible assets using the income approach (relief-from-royalty method) based on Level 3 inputs. The Company’s equity investment represents an investment in a non-controlled corporation without a readily determinable market value. The Company has elected to measure the investment at cost minus impairment, if any, plus or minus changes resulting from observable price changes. The fair value is determined by using quoted prices for identical or similar investments of the same issuer, which are Level 2 inputs. The Company recognizes changes to the fair value of its equity investment in interest expense, net, and other in the condensed consolidated statements of comprehensive income. The balance of the equity investment classified as Level 2 in the fair value hierarchy was $15,449 as of both June 30, 2020 and December 31, 2019. There were no changes to the fair value of the equity investment recognized during the three and six months ended June 30, 2020. There were no triggering events identified, no indication of impairment of the Company’s goodwill, indefinite-lived intangible assets, long-lived assets, or equity investments, and no impairment charges recorded during the six months ended June 30, 2020 and 2019. Fair Value of Financial Instruments The Company is required to disclose the fair value of financial instruments for which it is practicable to estimate the value, even though these instruments are not recognized at fair value in the consolidated balance sheets. The fair value of the Company’s 5.125% senior notes due 2024 (the “2024 Notes”) and 4.625% senior notes due 2027 (the “2027 Notes”) was estimated using quoted market prices in active markets for identical liabilities, which are Level 1 inputs. The carrying amounts and estimated fair value of the 2024 Notes and the 2027 Notes are presented in the following table. See additional information in “Item 8. Financial Statements and Supplementary Data—Notes to Consolidated Financial Statements—Note (8), Notes Payable and Credit Agreement” of the 2019 Annual Report.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The Company is subject to taxation in the U.S. and various states and foreign jurisdictions. With few exceptions, as of June 30, 2020, the Company is no longer subject to state, local or foreign examinations by tax authorities for tax years before 2010, and the Company is no longer subject to U.S. federal income or payroll tax examinations for tax years before 2016. Prior to the Company’s acquisition of Advanced, on June 14, 2019, Advanced was under an IRS audit for the years 2011-2013 for various payroll tax matters related to the treatment of certain non-taxable per diem allowances and travel benefits. This audit was completed and an assessment was issued for $8,300 in July 2018. The Company received a final determination from the IRS in November 2019 for $1,300. The Company is indemnified by Advanced for the potential contingent liability for all pre-acquisition open years. The Company acquired Stratus Video on February 14, 2020. The Company is indemnified by Stratus Video for any potential international income tax and contingent tax liability items for pre-acquisition open years up to $2,500. The Advanced and Stratus Video acquisitions are more fully described in Note (2), “Acquisitions.” The Company believes its indemnifications by Advanced and Stratus Video for all pre-acquisition years and its reserve for unrecognized tax benefits and contingent tax issues are adequate with respect to all open years. Notwithstanding the foregoing, the Company could adjust its provision for income taxes and contingent tax liability based on future developments.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES: LEGAL PROCEEDINGS	COMMITMENTS AND CONTINGENCIES: LEGAL PROCEEDINGSFrom time to time, the Company is involved in various lawsuits, claims, investigations, and proceedings that arise in the ordinary course of business. These matters typically relate to professional liability, tax, compensation, contract, competitor disputes and employee-related matters and include individual and class action lawsuits, as well as inquiries and investigations by governmental agencies regarding the Company’s employment and compensation practices. Additionally, some of the Company’s clients may also become subject to claims, governmental inquiries and investigations, and legal actions relating to services provided by the Company’s healthcare professionals. Depending upon the particular facts and circumstances, the Company may also be subject to indemnification obligations under its contracts with such clients relating to these matters. The Company records a liability when management believes an adverse outcome from a loss contingency is both probable and the amount, or a range, can be reasonably estimated. Significant judgment is required to determine both probability of loss and the estimated amount. The Company reviews its loss contingencies at least quarterly and adjusts its accruals and/or disclosures to reflect the impact of negotiations, settlements, rulings, advice of legal counsel, or other new information, as deemed necessary. The most significant matters for which the Company has established loss contingencies are class actions related to wage and hour claims under California and Federal law. Specifically, among other claims in these lawsuits, it is alleged that employees’ wage statements are not sufficiently clear, and certain expense reimbursements should be included in the regular rate of pay for purposes of calculating overtime rates. The Company believes that its wage and hour practices conform with law in all material respects, but litigation is always subject to inherent uncertainty and the Company is not able to reasonably predict if any matter will be resolved in a manner that is materially adverse to the Company beyond the amounts accrued. In addition, for the matters for which it is at least reasonably possible that the estimated loss will change in the near term, the Company is unable to currently estimate the possible loss or range of loss beyond the amounts already accrued. With regard to loss contingencies accrued as of June 30, 2020, which are included in accounts payable and accrued expenses in the condensed consolidated balance sheets, the Company believes that such matters will not, either individually or in the aggregate, have a material adverse effect on its business, consolidated financial position, results of operations, or cash flows.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Use of Estimates	The preparation of financial statements in conformity with U.S. GAAP requires management to make a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenue and expenses during the reporting periods. On an ongoing basis, the Company evaluates its estimates, including those related to intangible assets purchased in a business combination, asset impairments, accruals for self-insurance, compensation and related benefits, accounts receivable, contingencies and litigation, earn-out liabilities, and income taxes. Actual results could differ from those estimates under different assumptions or conditions.
Coronavirus Pandemic	Coronavirus Pandemic On March 11, 2020, the World Health Organization declared the outbreak of a novel strain of coronavirus, also known as COVID-19, a global pandemic. Due to the pandemic, there has been uncertainty and disruption in the global economy and significant volatility of financial markets. The Company is closely monitoring the impact of the pandemic, which continues to evolve, and its effects and risks on our operations, liquidity, financial condition and financial results for the full year 2020 and, possibly, beyond. The estimates used for, but not limited to, determining the collectability of accounts receivable, fair value of long-lived assets, and goodwill could be impacted by the pandemic. While the full impact of COVID-19, including the duration and severity of the pandemic, remains unknown, the Company has made appropriate estimates based on the facts and circumstances available as of the reporting date. Specifically, the Company continues to monitor the impacts of the pandemic on its customers’ liquidity and capital resources and, therefore, the Company’s ability to collect, or the timeliness of collection of accounts receivable. The impact of COVID-19 did not have a material effect on the Company’s estimates as of June 30, 2020. These estimates may change as new events occur and additional information is obtained. See additional information below regarding the allowance for credit losses for accounts receivable.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2016-13, “Measurement of Credit Losses on Financial Instruments.” The FASB also issued a series of other ASUs, which update ASU 2016-13 (collectively, the “credit loss standard”). This new standard introduces new accounting models for determining and recognizing credit losses on certain financial instruments based on an estimate of current expected credit losses. The Company adopted this standard effective January 1, 2020 using the modified retrospective transition method. The Company recognized the cumulative effect of adopting this guidance as an adjustment to the opening balance of retained earnings of $1,154, net of tax, primarily related to its allowance for credit losses for accounts receivable. Prior period amounts are not retrospectively adjusted. The impact of the adoption of the new standard was not material to the Company’s condensed consolidated financial statements for the three and six months ended June 30, 2020. The Company expects the impact to be immaterial on an ongoing basis. See additional information below regarding the allowance for credit losses for accounts receivable. In January 2017, the FASB issued ASU 2017-04, “Simplifying the Test for Goodwill Impairment.” The standard simplifies the subsequent measurement of goodwill by removing the requirement to perform a hypothetical purchase price allocation to compute the implied fair value of goodwill to measure impairment. Instead, any goodwill impairment will equal the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. Further, the guidance eliminates the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. The Company adopted this standard effective January 1, 2020 and the adoption did not have a material effect on the Company’s consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, “Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement.” The standard modifies the current disclosure requirements on fair value measurements. The Company adopted this standard effective January 1, 2020. Refer to information regarding fair value measurements in Note (7), “Fair Value Measurement.”
Cash, cash equivalents and restricted cash	Cash, cash equivalents and restricted cash The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents. Cash and cash equivalents include currency on hand, deposits with financial institutions and highly liquid investments. Restricted cash and cash equivalents primarily represent cash and money market funds on deposit with financial institutions and investments represents commercial paper that serves as collateral for the Company’s outstanding letters of credit and captive insurance subsidiary claim payments. See Note (7), “Fair Value Measurement” for additional information.
Accounts Receivable	Accounts Receivable The Company records accounts receivable at the invoiced amount. Accounts receivable are non-interest bearing. The Company maintains an allowance for expected credit losses based on the Company’s historical write-off experience, an assessment of its customers’ financial conditions and available information that is relevant to assessing the collectability of cash flows, which includes current conditions and forecasts about future economic conditions.
Reclassification	Reclassification The Company reclassified its allowance for accounts receivable in the prior year’s consolidated balance sheet to conform to the current year presentation. The prior year’s balance of accounts receivable (net of allowances) remains unchanged.
Revenue Recognition	Revenue primarily consists of fees earned from the temporary staffing and permanent placement of healthcare professionals, executives, and leaders (clinical and operational). The Company also generates revenue from its software as a service (“SaaS”)-based technologies, including vendor management systems and scheduling software, and outsourced workforce services, including language interpretation and recruitment process outsourcing. Revenue is recognized when control of these services is transferred to the customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those services. Revenue from temporary staffing services is recognized as the services are rendered by clinical and non-clinical healthcare professionals. Under the Company’s managed services program (“MSP”) arrangements, the Company manages all or a part of a customer’s supplemental workforce needs utilizing its own network of healthcare professionals along with those of third-party subcontractors. Revenue and the related direct costs under MSP arrangements are recorded in accordance with the accounting guidance on reporting revenue gross as a principal versus net as an agent. When the Company uses subcontractors and acts as an agent, revenue is recorded net of the related subcontractor’s expense. Revenue from permanent placement and outsourced workforce services is recognized as the services are rendered. Depending on the arrangement, the Company’s SaaS-based revenue is recognized either as the services are rendered or ratably over the applicable arrangement’s service period. The Company’s customers are primarily billed as services are rendered. Any fees billed in advance of being earned are recorded as deferred revenue. While payment terms vary by the type of customer and the services rendered, the term between invoicing and when payment is due is not significant. During the six months ended June 30, 2020 and 2019, previously deferred revenue recognized as revenue was $10,371 and $8,641, respectively. The Company has elected to apply the following practical expedients and optional exemptions related to contract costs and revenue recognition: • Recognize incremental costs of obtaining a contract with amortization periods of one year or less as expense when incurred. These costs are recorded within selling, general and administrative expenses. • Recognize revenue in the amount of consideration to which the Company has a right to invoice the customer if that amount corresponds directly with the value to the customer of the Company’s services completed to date. • Exemptions from disclosing the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less, (ii) contracts for which revenue is recognized in the amount of consideration to which the Company has a right to invoice for services performed and (iii) contracts for which variable consideration is allocated entirely to a wholly unsatisfied performance obligation or to a wholly unsatisfied promise to transfer a distinct service that forms part of a single performance obligation.
Net Income per Common Share	Basic net income per common share is calculated by dividing net income by the weighted average number of common shares outstanding during the reporting period.
Segment Information	The Company’s chief operating decision maker relies on internal management reporting processes that provide revenue and operating income by reportable segment for making financial decisions and allocating resources. Segment operating income represents income before income taxes plus depreciation, amortization of intangible assets, share-based compensation, interest expense, net, and other, and unallocated corporate overhead. The Company’s management does not evaluate, manage or measure performance of segments using asset information; accordingly, asset information by segment is not prepared or disclosed.
Fair Value of Financial Instruments	Assets and Liabilities Measured on a Recurring Basis The Company’s restricted cash equivalents that serve as collateral for the Company’s outstanding letters of credit typically consist of money market funds that are measured at fair value based on quoted prices, which are Level 1 inputs. The Company has a deferred compensation plan for certain executives and key employees, which is composed of deferred compensation and all related income and losses attributable thereto. The Company’s obligation under its deferred compensation plan is measured at fair value based on quoted market prices of the participants’ elected investments, which are Level 1 inputs. The Company’s restricted cash equivalents and investments that serve as collateral for the Company’s captive insurance company primarily consist of commercial paper that is measured at observable market prices for identical securities that are traded in less active markets, which are Level 2 inputs. Of the $52,752 commercial paper issued and outstanding as of June 30, 2020, $18,680 had original maturities greater than three months, which were considered available-for-sale securities. As of December 31, 2019, the Company had $59,243 commercial paper issued and outstanding, of which $9,586 had original maturities greater than three months and were considered available-for-sale securities. Assets Measured on a Non-Recurring Basis The Company applies fair value techniques on a non-recurring basis associated with valuing potential impairment losses related to its goodwill, indefinite-lived intangible assets, long-lived assets, and equity investments. The Company evaluates goodwill and indefinite-lived intangible assets annually for impairment and whenever circumstances occur indicating that goodwill might be impaired. The Company determines the fair value of its reporting units based on a combination of inputs, including the market capitalization of the Company, as well as Level 3 inputs such as discounted cash flows, which are not observable from the market, directly or indirectly. The Company determines the fair value of its indefinite-lived intangible assets using the income approach (relief-from-royalty method) based on Level 3 inputs. Fair Value of Financial Instruments The Company is required to disclose the fair value of financial instruments for which it is practicable to estimate the value, even though these instruments are not recognized at fair value in the consolidated balance sheets. The fair value of the Company’s 5.125% senior notes due 2024 (the “2024 Notes”) and 4.625% senior notes due 2027 (the “2027 Notes”) was estimated using quoted market prices in active markets for identical liabilities, which are Level 1 inputs. The carrying amounts and estimated fair value of the 2024 Notes and the 2027 Notes are presented in the following table. See additional information in “Item 8. Financial Statements and Supplementary Data—Notes to Consolidated Financial Statements—Note (8), Notes Payable and Credit Agreement” of the 2019 Annual Report. As of June 30, 2020 As of December 31, 2019 Carrying Estimated Carrying Estimated 2024 Notes $ 325,000 $ 323,375 $ 325,000 $ 337,188 2027 Notes 300,000 289,500 300,000 301,500
