Accounting Policies [Abstract]
Financial statement preparation	Financial statement preparation The accompanying unaudited consolidated financial statements (“financial statements”) of TrueBlue, Inc. (the "Company," "we," "us," "our," and "TrueBlue") are prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial information and rules and regulations of the Securities and Exchange Commission. Accordingly, certain information and footnote disclosures usually found in financial statements prepared in accordance with GAAP have been condensed or omitted. The financial statements reflect all adjustments which, in the opinion of management, are necessary to fairly state the financial statements for the interim periods presented. We follow the same accounting policies for preparing both quarterly and annual financial statements. These financial statements should be read in conjunction with the audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the fiscal year ended December 26, 2014. The results of operations for the twenty-six weeks ended June 26, 2015 are not necessarily indicative of the results expected for the full fiscal year or for any other fiscal period.
Recently issued accounting pronouncements not yet adopted	Recently issued accounting pronouncements not yet adopted In April 2015, the Financial Accounting Standards Board ("FASB") issued a new accounting standard intended to simplify the presentation of debt issuance costs. The standard requires that debt issuance costs related to a recognized debt liability be presented on the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with the presentation for debt discounts. The recognition and measurement guidance for debt issuance costs is not affected. This guidance is effective for annual periods beginning after December 15, 2015 (Q1 2016 for TrueBlue), including interim periods within those annual periods and must be applied on a retrospective basis with early adoption permitted. TrueBlue plans to adopt the new standard on the effective date. This standard is not expected to have a material impact on our consolidated financial statements. In April 2015, the FASB issued a new accounting standard designed to assist customers in their determination of whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The guidance will not change GAAP for a customer’s accounting for service contracts. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015 (Q1 2016 for TrueBlue). Early adoption is permitted and may be applied retrospectively or prospectively to arrangements entered into, or materially modified, after the effective date. TrueBlue plans to adopt the new standard prospectively on the effective date. This standard is not expected to have a material impact on our consolidated financial statements. In May 2014, the FASB issued a new accounting standard that sets forth a five-step revenue recognition model, which supersedes current revenue recognition guidance, including industry-specific revenue recognition guidance. The underlying principle of the new standard is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects what it expects in exchange for the goods or services. The standard also requires additional disclosure about the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. The new standard provides two methods of initial adoption: retrospective for all periods presented, or through a cumulative adjustment in the year of adoption. On July 9, 2015, the FASB approved a one year deferral of the effective date of the standard. The new effective date is for annual periods beginning after December 15, 2017 (Q1 2018 for TrueBlue), including interim periods within those annual periods. Early adoption is permitted one year prior to the effective date. We have not yet determined which method of adoption will be applied and are currently evaluating the impact that this standard will have on our consolidated financial statements.
