SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	Mar. 25, 2016
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 25, 2015. The results of operations for the thirteen weeks ended March 25, 2016 are not necessarily indicative of the results expected for the full fiscal year or for any other fiscal period.
New Accounting Pronouncement, Early Adoption [Table Text Block]	Recently adopted accounting standards Effective December 26, 2015, we early adopted the accounting standard that simplified the balance sheet disclosure of deferred income taxes retrospectively to all periods presented. This guidance requires deferred tax liabilities and assets to be classified as non-current in the Consolidated Balance Sheets. The guidance is effective for annual periods beginning after December 15, 2016, and may be applied either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. Early adoption is permitted. The adoption of this standard did not have a material impact to our financial statements.
Recently issued accounting pronouncements not yet adopted	Recently issued accounting pronouncements not yet adopted In March 2016, the Financial Accounting Standards Board ("FASB") issued guidance to improve employee share-based payment accounting. The simplifications impact several aspects, including the income tax consequences, classification of awards as equity or liabilities, and classification within the statement of cash flows. This guidance is effective for annual and interim periods beginning after December 15, 2016 (Q1 2017 for TrueBlue), and early adoption is permitted. We plan to adopt the guidance on the effective date. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements. In February 2016, the FASB issued guidance on lease accounting. The new guidance will continue to classify leases as either finance or operating and will result in the lessee recognizing a right-of-use asset and a corresponding lease liability on its balance sheet, with classification affecting the pattern of expense recognition in the statement of income. This guidance is effective for annual and interim periods beginning after December 15, 2018 (Q1 2019 for TrueBlue), and early adoption is permitted. A modified retrospective approach is required for all leases existing or entered into after the beginning of the earliest comparative period in the consolidated financial statements. We plan to adopt the guidance on the effective date. We are currently evaluating the impact of this guidance on our consolidated financial statements and expect that a majority of our operating lease commitments will be recognized on our consolidated balance sheets as operating lease liabilities and right-of-use assets upon adoption. In January 2016, the FASB issued guidance on the accounting for equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. The guidance is effective for annual periods beginning after December 15, 2017 (Q1 2018 for TrueBlue), including interim periods within that annual period. Early adoption of the amendments in the guidance is not permitted, with limited exceptions, and should be applied by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. We plan to adopt the guidance on the effective date. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements. In May 2014, the FASB issued guidance outlining a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers that supersedes most current revenue recognition guidance. This guidance requires an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance also requires enhanced disclosures, including revenue recognition policies to identify performance obligations to customers and significant judgments in measurement and recognition. The guidance 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 guidance provides two methods of initial adoption: retrospective for all periods presented, or through a cumulative adjustment in the year of adoption. In March 2016, the FASB issued additional guidance providing clarification on principal versus agent considerations included within the new revenue recognition guidance. The effective date is for annual periods beginning after December 15, 2017 (Q1 2018 for TrueBlue), including interim periods within those annual periods. We have not yet determined which method of adoption will be applied and are currently evaluating the impact that this guidance will have on our consolidated financial statements.
