Accounting Policies [Abstract]
Basis of Presentation and Accounting Policies	(1) Basis of Presentation and Accounting Policies Basis of Presentation Certain information and footnote disclosures normally included in the financial statements prepared in accordance with United States Generally Accepted Accounting Principles ("GAAP") have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission, although we believe that the disclosures are adequate to make the information presented not misleading. These Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements included in our 2019 Annual Report on Form 10-K. The information furnished reflects all adjustments that, in the opinion of management, were necessary for a fair statement of the Consolidated Financial Statements for the periods presented. Such adjustments were of a normal recurring nature, unless otherwise disclosed. COVID-19 The global spread of COVID-19, which was declared a global pandemic by the World Health Organization in March 2020, has created significant volatility, uncertainty and global macroeconomic disruption. Our business, operations and consolidated financial statements for the three and nine months ended September 30, 2020 were significantly negatively impacted by the COVID-19 crisis. By the end of March, significant lockdown measures had been implemented in our main markets in Europe and North America, as well as in certain other countries. At the beginning of the third quarter, it appeared the impact of the COVID-19 crisis was stabilizing in many parts of the world, and economies slowly reopened. However, as the third quarter came to a close, a number of countries started to see increased cases of COVID-19 that are leading to the implementation of new restrictions in an effort to mitigate the spread. Unlike the lockdowns and restrictions experienced earlier in the year, we do not anticipate the same country-wide lockdowns, but more targeted and localized restrictions. Continued uncertainty remains as to the future impact of the pandemic on global and local economies. We are continuing to monitor and assess the impacts of the COVID-19 pandemic and we expect that our financial condition, liquidity and future results of operations will continue to be adversely affected. However, we cannot predict with certainty what the impact will be on future periods. For further information on the impacts of COVID-19 on our business, operations and financial results, see Part I, Item 2: Management’s Discussion and Analysis of Financial Condition and Results of Operations. Allowance for Doubtful Accounts We have an allowance for doubtful accounts recorded as an estimate of the accounts receivable that may not be collected. This allowance is calculated on an entity-by-entity basis with consideration of historical write-off experience, age of receivables, market conditions, and a specific review for potential bad debts. Items that affect this balance mainly include bad debt expense and the write-off of accounts receivable balances. A rollforward of our allowance for doubtful accounts is shown below: Nine Months Ended September 30, 2020 Balance, December 31, 2019 $ 113.5 Provisions charged to earnings 17.8 Write-offs (12.7 ) Translation adjustments 3.5 Reclassifications and other 3.2 Balance, September 30, 2020 $ 125.3 Leases We determine whether a contract is or contains a lease at contract inception. Right-of-use (“ROU”) assets and long-term lease liabilities are presented as separate line items on our Consolidated Balance Sheets. Current operating lease liabilities are included in accrued expenses on our Consolidated Balance Sheets. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Lease liabilities are recognized at commencement date based on the present value of remaining lease payments over the lease term. As the rate implicit in the lease is not readily determinable in most of our leases, we use our incremental borrowing rate. We determine our incremental borrowing rate at the commencement date using our unsecured borrowing rate, adjusted for collateralization , lease term, economic environment, currency and other factors. ROU assets are recognized at commencement date at the value of the related lease liabilities, adjusted for any prepayments, lease incentives received, and initial direct costs incurred. Our lease terms include options to renew or not terminate the lease when it is reasonably certain that we will exercise that option. Lease expenses for operating leases are recognized on a straight-line basis over the lease term and recorded in selling and administrative expenses on the Consolidated Statements of Operations. Payroll Tax Credit In April 2019, we sold a portion of our French payroll tax credits earned in 2018 for net proceeds of $103.5 (€92.0). We derecognized these receivables and the additional interest upon the sale date as the terms of the agreement are such that the transaction qualifies for sale treatment in accordance with the accounting guidance on the transfer and servicing of assets. The discount on the sale of these receivables was recorded in cost of services as a reduction of the payroll tax credits. Goodwill Impairment In accordance with the accounting guidance on goodwill, we perform an annual impairment test of goodwill at our reporting unit level during the third quarter, or more frequently if events or circumstances change that would more likely than not reduce the fair value of our reporting units below their carrying value. We evaluate the recoverability of goodwill utilizing an income approach that estimates the fair value of the future discounted cash flows to which the goodwill relates. This approach reflects management’s internal outlook of the reporting units, which is believed to be the best determination of value due to management’s insight and experience with the reporting units. Significant assumptions used in our goodwill impairment tests include: expected future revenue growth rates, operating unit profit margins, working capital levels, discount rates, and a terminal value multiple. For the second quarter of 2020, in connection with the preparation of our quarterly financial statements, we assessed the changes in circumstances that occurred during the quarter to determine if it was more likely than not that the fair value of any reporting unit was below its carrying amount. We identified several factors related to our Germany reporting unit that led us to conclude that it was more likely than not that the fair value of the reporting unit was below its carrying amount. These factors included sustained operating losses resulted from the ongoing decline and increased uncertainty in the outlook of the manufacturing sector, particularly the automotive sector in Germany, coupled with the significant implications of COVID-19. As we determined that it was more likely than not that the fair value of the Germany reporting unit was below its carrying amount, we performed an interim impairment test on this reporting unit as of June 30, 2020. As a result of our interim test, we recognized a non-cash impairment loss of $66.8, which resulted in full impairment of the remaining goodwill in the Germany reporting unit. The Germany reporting unit is included in the Northern Europe segment. The goodwill impairment charge resulted from reductions in the estimated fair value for our Germany reporting unit based on lower expectations for future revenue, profitability and cash flows as compared to the expectations of the 2019 annual goodwill impairment test and our quarterly assessments in the intervening periods due to the factors discussed above. We performed our annual impairment test of our goodwill and indefinite-lived intangible assets during the third quarter of 2020 and determined that there was no impairment of our goodwill or indefinite-lived intangible assets. During the second quarter of 2019, we determined that it was more likely than not that the fair value of the Germany reporting unit was below its carrying amount and performed an interim goodwill impairment test. As a result of the interim test, we wrote down the carrying value of the Germany reporting unit to its estimated fair value and recognized a non-cash impairment charge loss of $60.2 during the second quarter of 2019. The table below provides our reporting units’ estimated fair values and carrying values, determined as part of our annual goodwill impairment test performed in the third quarter, representing approximately 80% of our consolidated goodwill balance as of September 30, 2020. (in millions) France United States Right Management United Kingdom Canada Netherlands Estimated fair values $ 2,367.8 $ 1,194.0 $ 383.3 $ 360.9 $ 153.2 $ 84.5 Carrying values 1,320.7 758.2 117.9 321.5 84.9 81.8 The fair value of each reporting unit was at least 20% in excess of the respective reporting unit’s carrying value with the exception of the United Kingdom and Netherlands reporting units. The United Kingdom reporting unit had a fair value exceeding carrying value of approximately 12%. Key assumptions included in the United Kingdom (Northern Europe Segment) discounted cash flow valuation performed during the third quarter of 2020 were a discount rate of 11.5%, a terminal value revenue growth rate of 1.0%, and a terminal value OUP margin of 3.1%. The Netherlands reporting unit fair value exceeded its carrying value by less than 10%, approximating 3.3%. The Netherlands is part of the Northern Europe Segment. Key assumptions included in the Netherlands discounted cash flow valuation performed during the third quarter of 2020 included a discount rate of 10.9%, a terminal value revenue growth rate of 2.0%, and a terminal value OUP margin of 3.5%. Should the operations of the business incur significant declines in profitability and cash flow due to significant and long-term deterioration in macroeconomic, industry and market conditions, some or all of the recorded goodwill for the Netherlands reporting unit, which was $114.5 million as of September 30, 2020, could be subject to impairment. While our other reporting units fair values exceeded 10% or more of their respective carrying values, given the uncertainty of the financial impacts from the COVID-19 pandemic, there may be further decreases in the operating results of our reporting units for a sustained period, which may result in a recognition of goodwill impairment that could be material to the Consolidated Financial Statements.

Accounting Changes And Error Corrections [Abstract]
Recent Accounting Standards	(2) Recent Accounting Standards Accounting Standards Effective as of January 1, 2020 In June 2016, the FASB issued new accounting guidance on financial instruments. The new guidance requires application of an impairment model known as the current expected credit loss (“CECL”) model to certain financial instruments. Using the CECL model, an entity recognizes an allowance for expected credit losses based on historical experience, current conditions, and forecasted information rather than the previous methodology of delaying recognition of credit losses until it is probable that loss has been incurred. The new guidance was effective for us as of January 1, 2020. The adoption of this guidance did not have a material impact on our Consolidated Financial Statements. In August 2018, the FASB issued new guidance on disclosures related to fair value measurements. The guidance is intended to improve the effectiveness of the notes to financial statements by facilitating clearer communication, and it includes multiple new, eliminated and modified disclosure requirements. The guidance was effective for us as of January 1, 2020. The adoption of this guidance had no impact on our Consolidated Financial Statements. In August 2018, the FASB issued new guidance on the accounting for internal-use software. The guidance aligns the accounting for costs incurred to implement a cloud computing arrangement that is a service arrangement with the guidance on capitalizing costs associated with developing or obtaining internal-use software. The guidance was effective for us as of January 1, 2020. The adoption of this guidance had no impact on our Consolidated Financial Statements. In August 2018, the FASB issued new guidance on disclosures related to defined benefit plans. The guidance amends the current disclosure requirements to add, remove and clarify disclosure requirements for defined benefit pension and other postretirement plans. The guidance was effective for us as of January 1, 2020. The adoption of this guidance had no impact on our Consolidated Financial Statements . Recently Issued Accounting Standards In December 2019, the FASB issued new guidance on income taxes. The guidance removes certain exceptions to the general income tax accounting principles, and clarifies and amends existing guidance to facilitate consistent application of the accounting principles. The new guidance is effective for us as of January 1, 2021. We are assessing the impact of the adoption of this guidance on our Consolidated Financial Statements. In January 2020, the FASB issued new guidance on equity method investments. The guidance clarifies the interactions between the existing accounting standards on equity securities, equity method and joint ventures, and derivatives and hedging. The new guidance addresses accounting for the transition into and out of the equity method and measuring certain purchased options and forward contracts to acquire investments. The new guidance is effective for us as of January 1, 2021. We do not expect the adoption of this guidance to have a material impact on our Consolidated Financial Statements.

Revenue From Contract With Customer [Abstract]
Revenue Recognition	(3) Revenue Recognition For certain client contracts where we recognize revenues over time, we recognize the amount that we have the right to invoice, which corresponds directly to the value provided to the client of our performance to date. We do not disclose the amount of unsatisfied performance obligations for client contracts with an original expected length of one year or less and those client contracts for which we recognize revenues at the amount to which we have the right to invoice for services performed. We have other contracts with revenues expected to be recognized subsequent to September 30, 2020, related to remaining performance obligations, which are not material. We record accounts receivable when our right to consideration becomes unconditional. Contract assets primarily relate to our rights to consideration for services provided that they are conditional on satisfaction of future performance obligations. We record contract liabilities (deferred revenue) when payments are made or due prior to the related performance obligations being satisfied. The current portion of our contract liabilities is included in accrued liabilities in our Consolidated Balance Sheets. We do not have any material contract assets or long-term contract liabilities. Our deferred revenue was $34.2 at September 30, 2020 and $44.5 at December 31, 2019. In the following table, revenue is disaggregated by service types for each of our reportable segments.

The expense relates to stock options, deferred stock, restricted stock and performance share units. We recognize share-based compensation expense in selling and administrative expenses on a straight-line basis over the service period of each award. Consideration received from share-based awards was $7.4 and $6.3 for the nine months ended September 30, 2020 and 2019, respectively.

Business Combinations [Abstract]
Acquisitions and Dispositions	(5) Acquisitions and Dispositions From time to time, we acquire and invest in companies throughout the world, including franchises. For the nine months ended September 30, 2020, the total cash consideration paid for acquisitions, net of cash acquired, was $1.7, which represents a deferred consideration payment related to a previous acquisition. On September 30, 2020 we disposed of four businesses (Serbia, Croatia, Slovenia, Bulgaria) in our Southern Europe segment for net proceeds of $5.8, subject to normal post close working capital adjustments and simultaneously entered into franchise agreements with the new ownership of these businesses. In connection with the disposition we recognized a one-time loss on disposition of $5.8, which was included in the selling and administrative expenses in the Consolidated Statement of Operations for the three and nine months ended September 30, 2020. Switzerland Acquisitions On April 3, 2019, we acquired the remaining 51 % controlling interest in our Swiss franchise (“Manpower Switzerland”) to obtain full ownership of the entity. Additionally, as part of the purchase agreement we acquired the remaining 20 % interest in Experis AG. Manpower Switzerland provides contingent staffing services under our Manpower brand in the four main language regions in Switzerland. Both Manpower Switzerland and Experis AG are reported in our Southern Europe segment. The aggregate cash consideration paid was $ as of September 30 , 2019 and was funded through cash on hand. Of the total consideration paid, $ 58.3 was for the acquired interests and the remaining $ was for cash and cash equivalents. The aggregate cash consideration paid reflects a post-closing settlement of net debt and net working capital adjustments of $ 6.8 , which we paid out during the third quarter of 2019. The total cash impact of the acquisition was an inflow of $ , net of cash acquired of $ 317.5 . The acquisition of the remaining interest of Experis AG was accounted for as an equity transaction as we previously consolidated the entity. In connection with the business combination, we recognized a one-time, non-cash gain on the disposition of our previously held equity interest in Manpower Switzerland of $80.4, which is included within interest and other expenses (income), net on the Consolidated Statements of Operations. Of the $80.4, $32.5 represented the reclassification of foreign currency translation adjustments related to the previously held equity interest, from accumulated other comprehensive income. Excluding Manpower Switzerland and Experis AG, the total cash consideration paid for acquisitions, net of cash acquired, was $39.5 for the nine months ended September 30, 2019. This balance represents contingent consideration payments related to previous acquisitions, of which $13.0 had been recognized as a liability at the acquisition date. ManpowerGroup Greater China Limited Disposition On July 10, 2019, our joint venture in Greater China, ManpowerGroup Greater China Limited, became listed on the Main Board of the Stock Exchange of Hong Kong Limited through an initial public offering. Prior to the initial public offering, we owned a 51% controlling interest in the joint venture and consolidated the financial position and results of its operations into our Consolidated Financial Statements as part of our APME segment. As a result of the offering, in which ManpowerGroup Greater China Limited issued new shares representing 25% of the equity of the company, our ownership interest was diluted to 38.25%, and then further diluted to 36.87% as the underwriters exercised their overallotment option in full on August 7, 2019. As a result, we deconsolidated the joint venture as of the listing date and account for the remaining interest under the equity method of accounting and record our share of equity income or loss in interest and other expenses (income), net in the Consolidated Statement of Operations. In connection with the deconsolidation of the joint venture, we recognized a one-time cash gain of $30.4, which was included in selling and administrative expenses in the Consolidated Statement of Operations in the quarter ended September 30, 2019. Included in the $30.4 was foreign currency translation adjustment losses of $6.2 related to the joint venture from accumulated other comprehensive income.

Restructuring Costs	(6) Restructuring Costs We recorded net restructuring costs of $98.1 and $42.5 during the nine months ended September 30, 2020 and 2019, respectively, in selling and administrative expenses, primarily related to severances and office closures and consolidations in multiple countries and territories. As a result of the adoption of the new accounting guidance on leases as of January 1, 2019, the office closure costs of $22.6 during the nine months ended September 30, 2020 were recorded as an impairment to the operating lease right-of-use asset and, thus, are not included in the restructuring reserve balance as of September 30, 2020. The costs paid, utilized or transferred out of our restructuring reserve were $55.5 during the nine months ended September 30, 2020. We expect a majority of the remaining $49.9 reserve will be paid by the end of 2020. Changes in the restructuring reserve by reportable segment and Corporate are shown below.

Income Tax Disclosure [Abstract]
Income Taxes	(7) Income Taxes We recorded income tax expense at an effective rate of 81.5% for the three months ended September 30, 2020, as compared to an effective rate of 28.6% for the three months ended September 30, 2019. The 2020 rate was unfavorably impacted by the relatively low level and mix of pre-tax earnings, tax losses in certain countries for which we did not recognize a corresponding tax benefit due to valuation allowances, including the recognition of a discrete valuation allowance in Germany, and the French business tax. The French business tax had a more significant unfavorable impact in the quarter due to French pre-tax earnings decreasing at a greater rate than revenues, which is the primary basis for the tax calculation. The effective tax rate of 81.5% for the three months ended September 30, 2020 was significantly higher than the United States Federal statutory rate of 21% primarily due to the factors noted above. We recorded income tax expense at an effective rate of 407.4% for the nine months ended September 30, 2020, as compared to an effective rate of 34.5% for the nine months ended September 30, 2019. The 2020 rate was unfavorably impacted by the relatively low level and mix of pre-tax earnings, tax losses in certain countries for which we did not recognize a corresponding tax benefit due to valuation allowances, including the recognition of a discrete valuation allowance in Germany, the non-deductible goodwill impairment charge in Germany, and the French business tax. The effective tax rate of 407.4% for the nine months ended September 30, 2020 was significantly higher than the United States Federal statutory rate of 21% primarily due to the factors noted above. As of September 30, 2020, we had gross unrecognized tax benefits related to various tax jurisdictions, including interest and penalties, of $68.2 that would favorably impact the effective tax rate if recognized. As of December 31, 2019, we had gross unrecognized tax benefits related to various tax jurisdictions, including interest and penalties, of $69.5. We do not expect our unrecognized tax benefits to change significantly over the next 12 months. We conduct business globally in various countries and territories. We are routinely audited by the tax authorities of the various tax jurisdictions in which we operate. Generally, the tax years that could be subject to examination are 2013 through 2020 for our major operations in France, Germany, Japan, the United Kingdom and the United States. As of September 30, 2020, we are subject to tax audits in Austria, Belgium, Canada, Denmark, France, Germany, Israel and the United States. We believe that the resolution of these audits will not have a material impact on earnings.

There were 0.7 million and 0.4 million share-based awards excluded from the calculation of net earnings per share - diluted for the three months ended September 30, 2020 and 2019, respectively, and 1.5 million and 0.4 million share-based awards excluded from the calculation of net earnings (loss) per share - diluted for the nine months ended September 30, 2020 and 2019, respectively, because their impact was anti-dilutive.

(4) The majority of the Corporate balance relates to goodwill attributable to our acquisitions of Right Management ($62.1) and Jefferson Wells ($55.5). Jefferson Wells is part of the United States reporting unit. For purposes of monitoring our total assets by segment, we do not allocate the Corporate balance to the respective reportable segments as this is commensurate with how we operate our business. We do, however, include these balances within the appropriate reporting units for our goodwill impairment testing. See table below for the breakout of goodwill balances by reporting unit. Goodwill balances by reporting unit were as follows: September 30, December 31, 2020 2019 United States $ 545.7 $ 545.8 Netherlands 114.5 109.5 United Kingdom 94.7 97.3 France 70.3 67.3 Right Management 62.1 62.1 Germany — 67.2 Other reporting units 311.3 310.9 Total goodwill $ 1,198.6 $ 1,260.1

During 2020, we expect to make total contributions of approximately $17.6 to our pension plans and to fund our retiree health care payments as incurred. Pension Settlement During the nine months ended September 30, 2020, we fully settled our United States Qualified Retirement Plan (the “Plan”) liability. We purchased annuities of $19.2 and settled lump sum payments of $3.2 from the Plan in January and February 2020, respectively. The completion of lump sum payments in February and transfer of remaining participants to the Pension Benefit Guarantee Corporation (PBGC) in March triggered final settlement of the plan. Upon settlement of the pension liability, we reclassified the related pension losses of $6.6, net of tax, recorded in accumulated other comprehensive loss to the Consolidated Statements of Comprehensive (Loss) Income. The total amount of the required payout to plan participants was determined based on employee elections and market conditions at the time of settlement. The remaining plan assets of $16.6 which were in excess of the pension liability upon settlement will be utilized to fund future qualified 401(k) plan contributions following the conclusion of the standard PBGC audit.

Derivative Financial Instruments and Fair Value Measurements	9 Months Ended

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments and Fair Value Measurements	(13) Derivative Financial Instruments and Fair Value Measurements Derivative Financial Instruments We are exposed to various market risks relating to our ongoing business operations. The primary market risks, which are managed using derivative instruments, are foreign currency exchange rate risk and interest rate risk. In certain circumstances, we enter into foreign currency forward exchange contracts (“forward contracts”) and cross-currency swaps to reduce the effects of fluctuating foreign currency exchange rates on our cash flows denominated in foreign currencies. Our exposure to market risk for changes in interest rates relates primarily to our long-term debt obligations. We have historically managed interest rate risk through the use of a combination of fixed and variable rate borrowings. Net Investment Hedges We use cross-currency swaps, forward contracts and a portion of our foreign currency denominated debt, a non-derivative financial instrument, to protect the value of our net investments in certain of our foreign subsidiaries. For derivative instruments that are designated and qualify as hedges of our net investments in foreign operations, the changes in fair values of the derivative instruments are recognized in foreign currency translation, a component of accumulated other comprehensive income (“AOCI”), to offset the changes in the values of the net investments being hedged. For non-derivative financial instruments that are designated and qualify as hedges of net investments in foreign operations, the change in the carrying value of the designated portion of the non-derivative financial instrument due to changes in foreign currency exchange rates is recorded in foreign currency translation adjustments. The €400.0 ($467.8) notes due September 2022 and the €500.0 ($581.8) notes due June 2026 were designated as a hedge of our net investment in our foreign subsidiaries with a Euro-functional currency as of September 30, 2020. In September 2019, we entered into a cross-currency swap agreement that net converts fixed-rate Swiss franc (“CHF”) payments to fixed-rate United States dollar payments. This swap was designated as a net investment hedge of our foreign subsidiary with CHF functional currency. The effect of our net investment hedges on AOCI for the three and nine months ended September 30, 2020 and 2019 was as follows: Gain (Loss) Recognized in Other Comprehensive Income 3 Months Ended September 30, 9 Months Ended September 30, Instrument 2020 2019 2020 2019 Euro Notes $ (43.8 ) $ 42.6 $ (45.7 ) $ 51.1 Cross-currency swaps (11.3 ) 2.8 (8.9 ) 2.8 Cash Flow Hedges We use cross-currency swaps to hedge the changes in cash flows of certain of our foreign currency denominated debt due to changes in foreign currency exchange rates. For our cross-currency swaps, we record the change in carrying value of the foreign currency denominated debt due to changes in exchange rates into earnings each period. The changes in fair value of the cross-currency swap derivatives are recorded in AOCI with an immediate reclassification into earnings for the change in fair value attributable to fluctuations in foreign currency exchange rates. In April 2019, we entered into a cross-currency swap agreement to convert our intercompany fixed-rate, CHF denominated note, including the annual interest payment and the payment of remaining principal at maturity, to a fixed-rate Euro denominated note. The economic effect of the swap agreement is to eliminate the uncertainty of cash flows in CHF associated with the note by fixing the principal at €202.3 with a fixed annual interest rate of 1.256%. This hedging arrangement has been designated as a cash flow hedge. The swap matures in April 2022, which matches the term of the intercompany note. Gains and losses from the hedge offset the changes in the value of principal and interest payments as a result of changes in foreign exchange rates. In September 2019 we entered into a cross-currency swap agreement to convert an additional intercompany fixed-rate CHF note, including the annual interest payment and the payment of remaining principal at maturity, to a fixed-rate Euro denominated note. The economic effect of the swap is identical to the original April 2019 swap, and fixes the principal of €55.4 with a fixed interest rate of 1.143%. The swap matures in September 2022, which matches the term of the intercompany note. We assessed the hedging relationship at the inception of the hedge in order to determine whether the derivatives that are used in the hedging transaction are highly effective in offsetting the cash flows of the hedged item and will continue to assess the relationship on an ongoing basis. We use the hypothetical derivative method in conjunction with regression analysis using a third-party valuation to measure effectiveness of our cross-currency swap agreement. The following tables present the impact that changes in the fair values of derivatives designated as cash flow hedges had on other comprehensive income (“OCI”), AOCI and earnings for the three and nine months ended September 30, 2020 and 2019: (Loss) Gain Reclassified (Loss) Gain Recognized in OCI from AOCI into Income 3 Months Ended September 30, Location of (Loss) Gain Reclassified 3 Months Ended September 30, Instrument 2020 2019 from AOCI into Income 2020 2019 Cross-currency swaps $ (3.2 ) $ 4.2 Interest and other expenses (income), net $ (3.3 ) $ 4.6 (Loss) Gain Reclassified (Loss) Gain Recognized in OCI from AOCI into Income 9 Months Ended September 30, Location of (Loss) Gain Reclassified 9 Months Ended September 30, Instrument 2020 2019 from AOCI into Income 2020 2019 Cross-currency swaps $ 1.6 $ 9.2 Interest and other expenses (income), net $ 1.4 $ 10.0 We expect the net amount of pre-tax derivative gains included in AOCI at September 30, 2020 to be reclassified into earnings within the next 12 months will not be significant. The actual amount that will be reclassified to earnings over the next 12 months will vary due to future currency exchange rates. Non-designated instruments We also use certain derivatives, which are not designated as hedging instruments, as economic hedges of foreign currency and interest rate exposure. For our forward contracts that are not designated as hedges, any gain or loss resulting from the change in fair value is recognized in current period earnings. These gains or losses are offset by the exposure related to receivables and payables with our foreign subsidiaries and to interest due on our Euro-denominated notes, which is paid annually in June and September. The effect of our forward contracts that are not designated as hedging instruments on the consolidated statements of operations for the three and nine months ended September 30, 2020 was as follows: Location of Gain Amount of Gain Recognized in Income Instrument Recognized in Income 3 Months Ended September 30, 9 Months Ended September 30, 2020 2019 2020 2019 Foreign currency forward contracts Interest and other expenses (income), net $ — $ 4.6 $ 0.3 $ 13.8 The following tables present the fair value of derivative and non-derivative assets and liabilities on the Consolidated Balance Sheets as of September 30, 2020 and December 31, 2019: Assets September 30, December 31, Balance Sheet Location 2020 2019 Instruments designated as cash flow hedges: Cross-currency swaps Prepaid expenses and other assets $ 12.0 $ 9.7 Total instruments $ 12.0 $ 9.7 Liabilities September 30, December 31, Balance Sheet Location 2020 2019 Instruments designated as net investment hedges: Euro Notes Long-term debt $ 1,049.6 $ 1,002.9 Cross-currency swaps Accrued liabilities 16.1 6.0 Total instruments $ 1,065.7 $ 1,008.9 Fair Value Measurements The carrying value of the long-term debt approximates fair value, except for the Euro-denominated notes, because the interest rates are variable and reflect current market rates. The fair value of the Euro-denominated notes, as observable at commonly quoted intervals (Level 2 inputs), was $1,092.8 and $1,062.5 as of September 30, 2020 and December 31, 2019, respectively, compared to a carrying value of $1,049.6 and $1,002.9, respectively. Our deferred compensation plan assets were $109.7 and $107.3 as of September 30, 2020 and December 31, 2019 respectively. We determine the fair value of these assets, comprised of publicly traded securities, by using market quotes as of the last day of the period (Level 1 inputs). We measure the fair value of the foreign currency forward contracts and cross-currency swaps at the value based on either directly or indirectly observable inputs from third parties (Level 2 inputs).

Segment Reporting [Abstract]
Segment Data	(15) Segment Data Effective January 1, 2020, our segment reporting was realigned due to our Right Management business being combined with each of our respective country business units. Accordingly, our former reportable segment, Right Management, is now reported within each of our respective reportable segments. All previously reported results have been restated to conform to the current year presentation. We are organized and managed primarily on a geographic basis. Each country and business unit generally has its own distinct operations and management team, providing services under our global brands, and maintains its own financial reports. We have an executive sponsor for each global brand who is responsible for ensuring the integrity and consistency of delivery locally. Each operation reports directly or indirectly through a regional manager, to a member of executive management. Given this reporting structure, we operate using the following reporting segments: Americas, which includes United States and Other Americas; Southern Europe, which includes France, Italy and Other Southern Europe; Northern Europe; and APME. The segments derive a significant majority of their revenues from our staffing and interim services. The remaining revenues within these segments are derived from our outcome-based solutions and consulting services, permanent recruitment services, outplacement services, talent management services, and other services. Segment revenues represent sales to external clients. We provide services to a wide variety of clients, none of which individually comprise a significant portion of revenues for us as a whole. Due to the nature of our business, we generally do not have export sales. 3 Months Ended September 30, 9 Months Ended September 30, 2020 2019 2020 2019 Revenues from services: Americas: United States (a) $ 578.8 $ 666.4 $ 1,705.6 $ 1,942.3 Other Americas 350.3 428.1 1,071.1 1,250.6 929.1 1,094.5 2,776.7 3,192.9 Southern Europe: France 1,205.3 1,386.4 3,035.1 4,117.8 Italy 351.2 376.9 947.4 1,127.7 Other Southern Europe 555.9 594.5 1,545.4 1,615.4 2,112.4 2,357.8 5,527.9 6,860.9 Northern Europe 947.7 1,166.8 2,881.9 3,561.4 APME 595.6 629.8 1,759.6 2,051.7 Consolidated (b) $ 4,584.8 $ 5,248.9 $ 12,946.1 $ 15,666.9 Operating unit profit (loss): (c) Americas: United States $ 19.3 $ 39.8 $ 30.8 94.1 Other Americas 12.2 19.5 37.0 52.5 31.5 59.3 67.8 146.6 Southern Europe: France 51.5 70.3 87.0 201.3 Italy 15.4 23.3 40.6 73.4 Other Southern Europe 4.7 22.8 9.1 51.9 71.6 116.4 136.7 326.6 Northern Europe (22.5 ) 22.8 (36.3 ) 50.3 APME 16.7 54.9 51.6 105.2 97.3 253.4 219.8 628.7 Corporate expenses (29.1 ) (29.2 ) (83.5 ) (89.0 ) Goodwill impairment charges - - (66.8 ) (64.0 ) Intangible asset amortization expense (6.6 ) (7.2 ) (20.2 ) (22.4 ) Operating profit 61.6 217.0 49.3 453.3 Interest and other (expenses) income, net (6.0 ) (12.2 ) (32.3 ) 46.1 Earnings before income taxes $ 55.6 $ 204.8 $ 17.0 $ 499.4 (a) In the United States, revenues from services included fees received from the related franchise offices of $3.4 and $3.5 for the three months ended September 30, 2020 and 2019, respectively, and $8.8 and $10.8 for the nine months ended September 30, 2020 and 2019, respectively. These fees are primarily based on revenues generated by the franchise offices, which were $116.9 and $151.6 for the three months ended September 30, 2020 and 2019, respectively, and $315.7 and $462.8 for the nine months ended September 30, 2020 and 2019, respectively.

These fees are primarily based on revenues generated by the franchise offices, which were $236.9 and $274.0 for the three months ended September 30, 2020 and 2019, respectively, and $447.3 and $680.2 for the nine months ended September 30, 2020 and 2019, respectively. (c) We evaluate segment performance based on operating unit profit (“OUP”), which is equal to segment revenues less cost of services and branch and national headquarters operating costs. This profit measure does not include goodwill and intangible asset impairment charges or amortization of intangibles related to acquisitions, corporate expenses, interest and other income and expense amounts or income taxes.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation Certain information and footnote disclosures normally included in the financial statements prepared in accordance with United States Generally Accepted Accounting Principles ("GAAP") have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission, although we believe that the disclosures are adequate to make the information presented not misleading. These Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements included in our 2019 Annual Report on Form 10-K. The information furnished reflects all adjustments that, in the opinion of management, were necessary for a fair statement of the Consolidated Financial Statements for the periods presented. Such adjustments were of a normal recurring nature, unless otherwise disclosed.
COVID-19	COVID-19 The global spread of COVID-19, which was declared a global pandemic by the World Health Organization in March 2020, has created significant volatility, uncertainty and global macroeconomic disruption. Our business, operations and consolidated financial statements for the three and nine months ended September 30, 2020 were significantly negatively impacted by the COVID-19 crisis. By the end of March, significant lockdown measures had been implemented in our main markets in Europe and North America, as well as in certain other countries. At the beginning of the third quarter, it appeared the impact of the COVID-19 crisis was stabilizing in many parts of the world, and economies slowly reopened. However, as the third quarter came to a close, a number of countries started to see increased cases of COVID-19 that are leading to the implementation of new restrictions in an effort to mitigate the spread. Unlike the lockdowns and restrictions experienced earlier in the year, we do not anticipate the same country-wide lockdowns, but more targeted and localized restrictions. Continued uncertainty remains as to the future impact of the pandemic on global and local economies. We are continuing to monitor and assess the impacts of the COVID-19 pandemic and we expect that our financial condition, liquidity and future results of operations will continue to be adversely affected. However, we cannot predict with certainty what the impact will be on future periods. For further information on the impacts of COVID-19 on our business, operations and financial results, see Part I, Item 2: Management’s Discussion and Analysis of Financial Condition and Results of Operations.
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts We have an allowance for doubtful accounts recorded as an estimate of the accounts receivable that may not be collected. This allowance is calculated on an entity-by-entity basis with consideration of historical write-off experience, age of receivables, market conditions, and a specific review for potential bad debts. Items that affect this balance mainly include bad debt expense and the write-off of accounts receivable balances. A rollforward of our allowance for doubtful accounts is shown below: Nine Months Ended September 30, 2020 Balance, December 31, 2019 $ 113.5 Provisions charged to earnings 17.8 Write-offs (12.7 ) Translation adjustments 3.5 Reclassifications and other 3.2 Balance, September 30, 2020 $ 125.3
Leases	Leases We determine whether a contract is or contains a lease at contract inception. Right-of-use (“ROU”) assets and long-term lease liabilities are presented as separate line items on our Consolidated Balance Sheets. Current operating lease liabilities are included in accrued expenses on our Consolidated Balance Sheets. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Lease liabilities are recognized at commencement date based on the present value of remaining lease payments over the lease term. As the rate implicit in the lease is not readily determinable in most of our leases, we use our incremental borrowing rate. We determine our incremental borrowing rate at the commencement date using our unsecured borrowing rate, adjusted for collateralization , lease term, economic environment, currency and other factors. ROU assets are recognized at commencement date at the value of the related lease liabilities, adjusted for any prepayments, lease incentives received, and initial direct costs incurred. Our lease terms include options to renew or not terminate the lease when it is reasonably certain that we will exercise that option. Lease expenses for operating leases are recognized on a straight-line basis over the lease term and recorded in selling and administrative expenses on the Consolidated Statements of Operations.
Payroll Tax Credit	Payroll Tax Credit In April 2019, we sold a portion of our French payroll tax credits earned in 2018 for net proceeds of $103.5 (€92.0). We derecognized these receivables and the additional interest upon the sale date as the terms of the agreement are such that the transaction qualifies for sale treatment in accordance with the accounting guidance on the transfer and servicing of assets. The discount on the sale of these receivables was recorded in cost of services as a reduction of the payroll tax credits.
Goodwill Impairment	Goodwill Impairment In accordance with the accounting guidance on goodwill, we perform an annual impairment test of goodwill at our reporting unit level during the third quarter, or more frequently if events or circumstances change that would more likely than not reduce the fair value of our reporting units below their carrying value. We evaluate the recoverability of goodwill utilizing an income approach that estimates the fair value of the future discounted cash flows to which the goodwill relates. This approach reflects management’s internal outlook of the reporting units, which is believed to be the best determination of value due to management’s insight and experience with the reporting units. Significant assumptions used in our goodwill impairment tests include: expected future revenue growth rates, operating unit profit margins, working capital levels, discount rates, and a terminal value multiple. For the second quarter of 2020, in connection with the preparation of our quarterly financial statements, we assessed the changes in circumstances that occurred during the quarter to determine if it was more likely than not that the fair value of any reporting unit was below its carrying amount. We identified several factors related to our Germany reporting unit that led us to conclude that it was more likely than not that the fair value of the reporting unit was below its carrying amount. These factors included sustained operating losses resulted from the ongoing decline and increased uncertainty in the outlook of the manufacturing sector, particularly the automotive sector in Germany, coupled with the significant implications of COVID-19. As we determined that it was more likely than not that the fair value of the Germany reporting unit was below its carrying amount, we performed an interim impairment test on this reporting unit as of June 30, 2020. As a result of our interim test, we recognized a non-cash impairment loss of $66.8, which resulted in full impairment of the remaining goodwill in the Germany reporting unit. The Germany reporting unit is included in the Northern Europe segment. The goodwill impairment charge resulted from reductions in the estimated fair value for our Germany reporting unit based on lower expectations for future revenue, profitability and cash flows as compared to the expectations of the 2019 annual goodwill impairment test and our quarterly assessments in the intervening periods due to the factors discussed above. We performed our annual impairment test of our goodwill and indefinite-lived intangible assets during the third quarter of 2020 and determined that there was no impairment of our goodwill or indefinite-lived intangible assets. During the second quarter of 2019, we determined that it was more likely than not that the fair value of the Germany reporting unit was below its carrying amount and performed an interim goodwill impairment test. As a result of the interim test, we wrote down the carrying value of the Germany reporting unit to its estimated fair value and recognized a non-cash impairment charge loss of $60.2 during the second quarter of 2019. The table below provides our reporting units’ estimated fair values and carrying values, determined as part of our annual goodwill impairment test performed in the third quarter, representing approximately 80% of our consolidated goodwill balance as of September 30, 2020. (in millions) France United States Right Management United Kingdom Canada Netherlands Estimated fair values $ 2,367.8 $ 1,194.0 $ 383.3 $ 360.9 $ 153.2 $ 84.5 Carrying values 1,320.7 758.2 117.9 321.5 84.9 81.8 The fair value of each reporting unit was at least 20% in excess of the respective reporting unit’s carrying value with the exception of the United Kingdom and Netherlands reporting units. The United Kingdom reporting unit had a fair value exceeding carrying value of approximately 12%. Key assumptions included in the United Kingdom (Northern Europe Segment) discounted cash flow valuation performed during the third quarter of 2020 were a discount rate of 11.5%, a terminal value revenue growth rate of 1.0%, and a terminal value OUP margin of 3.1%. The Netherlands reporting unit fair value exceeded its carrying value by less than 10%, approximating 3.3%. The Netherlands is part of the Northern Europe Segment. Key assumptions included in the Netherlands discounted cash flow valuation performed during the third quarter of 2020 included a discount rate of 10.9%, a terminal value revenue growth rate of 2.0%, and a terminal value OUP margin of 3.5%. Should the operations of the business incur significant declines in profitability and cash flow due to significant and long-term deterioration in macroeconomic, industry and market conditions, some or all of the recorded goodwill for the Netherlands reporting unit, which was $114.5 million as of September 30, 2020, could be subject to impairment. While our other reporting units fair values exceeded 10% or more of their respective carrying values, given the uncertainty of the financial impacts from the COVID-19 pandemic, there may be further decreases in the operating results of our reporting units for a sustained period, which may result in a recognition of goodwill impairment that could be material to the Consolidated Financial Statements.
Recent Accounting Standards	(2) Recent Accounting Standards Accounting Standards Effective as of January 1, 2020 In June 2016, the FASB issued new accounting guidance on financial instruments. The new guidance requires application of an impairment model known as the current expected credit loss (“CECL”) model to certain financial instruments. Using the CECL model, an entity recognizes an allowance for expected credit losses based on historical experience, current conditions, and forecasted information rather than the previous methodology of delaying recognition of credit losses until it is probable that loss has been incurred. The new guidance was effective for us as of January 1, 2020. The adoption of this guidance did not have a material impact on our Consolidated Financial Statements. In August 2018, the FASB issued new guidance on disclosures related to fair value measurements. The guidance is intended to improve the effectiveness of the notes to financial statements by facilitating clearer communication, and it includes multiple new, eliminated and modified disclosure requirements. The guidance was effective for us as of January 1, 2020. The adoption of this guidance had no impact on our Consolidated Financial Statements. In August 2018, the FASB issued new guidance on the accounting for internal-use software. The guidance aligns the accounting for costs incurred to implement a cloud computing arrangement that is a service arrangement with the guidance on capitalizing costs associated with developing or obtaining internal-use software. The guidance was effective for us as of January 1, 2020. The adoption of this guidance had no impact on our Consolidated Financial Statements. In August 2018, the FASB issued new guidance on disclosures related to defined benefit plans. The guidance amends the current disclosure requirements to add, remove and clarify disclosure requirements for defined benefit pension and other postretirement plans. The guidance was effective for us as of January 1, 2020. The adoption of this guidance had no impact on our Consolidated Financial Statements . Recently Issued Accounting Standards In December 2019, the FASB issued new guidance on income taxes. The guidance removes certain exceptions to the general income tax accounting principles, and clarifies and amends existing guidance to facilitate consistent application of the accounting principles. The new guidance is effective for us as of January 1, 2021. We are assessing the impact of the adoption of this guidance on our Consolidated Financial Statements. In January 2020, the FASB issued new guidance on equity method investments. The guidance clarifies the interactions between the existing accounting standards on equity securities, equity method and joint ventures, and derivatives and hedging. The new guidance addresses accounting for the transition into and out of the equity method and measuring certain purchased options and forward contracts to acquire investments. The new guidance is effective for us as of January 1, 2021. We do not expect the adoption of this guidance to have a material impact on our Consolidated Financial Statements.
