Accounting Policies [Abstract]
Nature of Operations	Nature of Operations. Robert Half International Inc. (the “Company”) is a specialized talent solutions and business consulting firm that connects opportunities at great companies with highly skilled job seekers. Robert Half® offers contract talent solutions and permanent placement talent solutions for finance and accounting, technology, marketing and creative, legal, administrative and customer support roles. Robert Half is also the parent company of Protiviti®, a global consulting firm that provides internal audit, risk, business, and technology consulting solutions. The Company completed a multiyear process to unify its family of Robert Half endorsed divisional brands to a single brand, Robert Half. This simplifies the Company’s go-to-market brand structure for clients and candidates, provides leverage for greater brand awareness, and allows future flexibility to expand the Company’s existing functional specializations. In connection with this process, the Company’s current financial statement disclosures reflect new names for its reportable segments, including contract talent solutions (formerly temporary and consultant staffing), permanent placement talent solutions (formerly permanent placement staffing) and Protiviti (formerly risk consulting and internal audit services). What was previously referred to as staffing operations is now referred to as talent solutions. The presentation of contract talent solutions includes functional specializations rather than the previously branded divisions. The functional specializations are: finance and accounting, which combines the former Accountemps® and Robert Half® Management Resources divisions; administrative and customer support, which consists of the former OfficeTeam®; and technology, which includes the former Robert Half® Technology. The Company operates in North America, South America, Europe, Asia and Australia. The Company is a Delaware corporation.
Basis of Presentation	Basis of Presentation. The unaudited Condensed Consolidated Financial Statements (“Financial Statements”) of the Company are prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and the rules of the Securities and Exchange Commission (“SEC”).

Use of Estimates	Use of Estimates. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. As of September 30, 2022, such estimates include allowances for credit losses, variable consideration, workers’ compensation losses, accrued medical expenses, income and other taxes, assumptions used in the Company’s goodwill impairment assessment and in the valuation of stock grants subject to market conditions.
Service Revenues/Costs of Services	Service Revenues. The Company derives its revenues from three segments: contract talent solutions, permanent placement talent solutions, and Protiviti. Revenues are recognized when promised goods or services are delivered to customers in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. See Note C for further discussion of the revenue recognition accounting policy.Costs of Services. Direct costs of contract talent solutions consist of professional staff payroll, payroll taxes and benefit costs for the Company’s engagement professionals, as well as reimbursable expenses. Direct costs of permanent placement talent solutions consist of reimbursable expenses. Protiviti direct costs of services include professional staff payroll, payroll taxes and benefit costs, as well as reimbursable expenses.
Advertising Costs	Advertising Costs. The Company expenses all advertising costs as incurred.

Under the Company’s employee deferred compensation plans, employees direct the investment of their account balances, and the Company invests amounts held in the associated investment trusts consistent with these directions. As realized and unrealized investment gains and losses occur, the Company’s deferred compensation obligation to employees changes and adjustments are recorded in selling, general and administrative expenses or, in the case of Protiviti, costs of services. The value of the related investment trust assets also changes by an equal and offsetting amount, leaving no net cost to the Company. The Company’s (income) loss from investments held in employee deferred compensation trusts consists primarily of unrealized and realized gains and losses and dividend income from trust investments and is presented separately on the unaudited Condensed Consolidated Statements of Operations.
Comprehensive Income (Loss)	Comprehensive Income (Loss). Comprehensive income (loss) includes net income and certain other items that are recorded directly to stockholders’ equity. The Company’s only sources of other comprehensive income (loss) are foreign currency translation and foreign defined benefit plan adjustments.
Fair Value of Financial Instruments	Fair Value of Financial Instruments. Assets and liabilities recorded at fair value are measured and classified in accordance with a three-tier fair value hierarchy based on the observability of the inputs available in the market to measure fair value, summarized as follows: Level 1: observable inputs for identical assets or liabilities, such as quoted prices in active markets Level 2: inputs other than the quoted prices in active markets that are observable either directly or indirectly Level 3: unobservable inputs in which there is little or no market data, which requires management’s best estimates and assumptions that market participants would use in pricing the asset or liability The carrying value of cash and cash equivalents, net accounts receivable, and accounts payable and accrued expenses approximates fair value because of their short-term nature. The Company holds mutual funds and money market funds to satisfy its obligations under its employee deferred compensation plans, which are carried at fair value based on quoted market prices in active markets for identical assets (level 1).
Allowance for Credit Losses	Allowance for Credit Losses. The Company is exposed to credit losses resulting from the inability of its customers to make required payments. The Company establishes an allowance for these potential credit losses based on its review of customers’ credit profiles, historical loss statistics, prepayments, recoveries, age of customer receivable balances, current business conditions and macroeconomic trends. The Company considers risk characteristics of trade receivables based on asset type and geographical locations to evaluate trade receivables on a collective basis. The Company applies credit loss estimates to these pooled receivables to determine expected credit losses.

In November 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2021-10, “Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance” to increase the transparency of government assistance including the disclosure of the types of assistance an entity receives, an entity’s method of accounting for government assistance and the effect of the assistance on an entity’s financial statements.

The amendments should be applied either (1) prospectively to all transactions within the scope of the amendments that are reflected in financial statements at the date of initial application and new transactions that are entered into after the date of initial application, or (2) retrospectively to those transactions. The Company adopted this ASU in January 2022. The adoption of this guidance did not have a material impact on its financial statements. Recently Issued Accounting Pronouncements Not Yet Adopted None.
Commitments and Contingencies	Legal costs associated with the resolution of claims, lawsuits and other contingencies are expensed as incurred.
