Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Financial statement preparation The accompanying unaudited consolidated financial statements (“financial statements”) of TrueBlue, Inc. (the “company,” “TrueBlue,” “we,” “us,” and “our”) are prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and rules and regulations of the Securities and Exchange Commission for interim financial information. Accordingly, certain information and footnote disclosures usually found in financial statements prepared in accordance with U.S. 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. We also considered COVID-19 related impacts to our estimates, as appropriate, within our financial statements and there may be changes to those estimates in future periods. However, we believe that the accounting estimates used are appropriate after considering the increased uncertainties surrounding the severity and duration of COVID-19. These estimates and assumptions are subject to inherent uncertainties, which may result in actual future amounts differing from reported estimated amounts. 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 29, 2019. The results of operations for the thirteen and thirty-nine weeks ended September 27, 2020 are not necessarily indicative of the results expected for the full fiscal year or for any other fiscal period. Recently adopted accounting standards Credit losses In June 2016, the Financial Accounting Standards Board issued guidance on accounting for credit losses on financial instruments. This guidance sets forth a current expected credit loss model (“CECL”), which requires the measurement of credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The guidance requires the application of a current expected credit loss model, which is a new impairment model based on expected losses. Under this 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 a loss has been incurred. This guidance was adopted at the beginning of the first quarter of 2020. We were required to apply the new standard by means of a cumulative-effect adjustment to opening retained earnings as of the beginning of the first quarter of 2020. The total impact upon adoption to opening retained earnings was immaterial to both the individual financial assets affected as well as in the aggregate. The following policies have been updated to reflect our adoption of the new standard on accounting for credit losses on financial instruments. Accounts receivable and allowance for credit losses Accounts receivable are recorded at the invoiced amount. We establish an estimate for the allowance for credit losses resulting from the failure of our clients to make required payments by applying an aging schedule to pools of assets with similar risk characteristics. Based on an analysis of the risk characteristics of our clients and associated receivables, we have concluded our pools are as follows: • PeopleReady and Centerline Drivers (“Centerline”) have a large, diverse set of clients, generally with frequent, low dollar invoices due to the daily nature of the work we perform. This results in high turnover in accounts receivable and lower rates of non-payment. • PeopleManagement On-Site has a smaller number of clients, and follows a contractual billing schedule. The invoice amounts are higher than that of PeopleReady and Centerline, with longer payment terms. • PeopleScout has a smaller number of clients, and generally sends invoices on a consolidated basis for a client. Invoice amounts are generally higher for PeopleScout than for PeopleManagement On-Site, with similar payment terms. When specific clients are identified as no longer sharing the same risk profile as their current pool, they are removed from the pool and evaluated separately. The credit loss rates applied to each aging category by pool are based on current collection efforts, historical collection trends, write-off experience, client credit risk, current economic data and forecasted information. The allowance for credit loss is reviewed quarterly and represents our best estimate of the amount of expected credit losses. Each month, past due or delinquent balances are identified based upon a review of aged receivables performed by collections and operations. Past due balances are written off when it is probable the receivable will not be collected. Changes in the allowance for credit losses are recorded in selling, general and administrative (“SG&A”) expense on the Consolidated Statements of Operations and Comprehensive Income (Loss). Due to the uncertain economic environment, it is difficult to estimate the impact caused by COVID–19 on our clients. However, the allowance for credit loss for accounts receivable as of September 27, 2020 is our best estimate of the amount of expected credit losses. Should actual results deviate from what we have currently estimated, our allowance for credit losses could change significantly. The activity related to the allowance for credit losses for accounts receivable during the thirty-nine weeks ended September 27, 2020 was as follows: (in thousands) Beginning balance $ 4,288 Cumulative-effect adjustment (1) 524 Current period provision 6,582 Write-offs (5,925) Foreign currency translation (22) Ending balance $ 5,447 (1) As a result of our adoption of the accounting standard for credit losses, we recognized a cumulative-effect adjustment to our account receivable allowance of $0.5 million as of the beginning of the first quarter of 2020. Restricted cash and investments We establish an allowance for credit loss for our held-to-maturity debt securities using a discounted cash flow method including a probability of default rate based on the issuer’s credit rating. We report the entire change in present value as credit loss expense (or reversal of credit loss expense) in cost of services on the Consolidated Statements of Operations and Comprehensive Income (Loss). The cumulative-effect adjustment to our held-to-maturity debt securities as a result of adopting CECL as of the beginning of the first quarter of 2020 was immaterial, as was the allowance as of September 27, 2020. Workers’ compensation claims reserves We establish an allowance for credit loss for our insurance receivables using a probability of default and losses expected upon default method, with the probability of default rate based on the third-party insurance carrier’s credit rating. Changes in the allowance for credit losses are recorded in cost of services on the Consolidated Statements of Operations and Comprehensive Income (Loss). The cumulative-effect adjustment to our workers’ compensation insurance receivables as a result of adopting CECL as of the beginning of the first quarter of 2020 was immaterial, as was the allowance as of September 27, 2020. Reclassifications Certain previously reported amounts have been reclassified to conform to the current presentation. Specifically, the company has made certain reclassifications between cost of services and SG&A expense to more accurately reflect the costs of delivering our services. Such reclassifications did not have a significant impact on the company’s gross profit or SG&A expense. Certain immaterial prior year amounts have also been reclassified within cash flows from investing activities on our Consolidated Statements of Cash Flows to conform to current year presentation. Recently issued accounting pronouncements not yet adopted There are no accounting pronouncements which have not yet been adopted that are expected to have a significant impact on our financial statements and related disclosures.

Our insurance carriers and certain state workers’ compensation programs require us to collateralize a portion of our workers’ compensation obligation. The collateral typically takes the form of cash and cash equivalents and highly rated investment grade securities, primarily in debt and asset-backed securities. The majority of our collateral obligations are held in a trust at the Bank of New York Mellon (“Trust”). The amortized cost and estimated fair value of our held-to-maturity investments held in Trust, aggregated by investment category as of September 27, 2020 and December 29, 2019, were as follows: September 27, 2020 (in thousands) Amortized cost Gross unrealized gains Gross unrealized losses Fair value Municipal debt securities $ 68,716 $ 3,638 $ — $ 72,354 Corporate debt securities 85,629 2,605 (98) 88,136 Agency mortgage-backed securities 686 27 — 713 U.S. government and agency securities 999 140 — 1,139 Total held-to-maturity investments $ 156,030 $ 6,410 $ (98) $ 162,342 December 29, 2019 (in thousands) Amortized cost Gross unrealized gains Gross unrealized losses Fair value Municipal debt securities $ 72,017 $ 2,219 $ — $ 74,236 Corporate debt securities 75,000 1,102 (34) 76,068 Agency mortgage-backed securities 1,357 21 (2) 1,376 U.S. government and agency securities 999 52 — 1,051 Total held-to-maturity investments $ 149,373 $ 3,394 $ (36) $ 152,731 The amortized cost and fair value by contractual maturity of our held-to-maturity investments are as follows: September 27, 2020 (in thousands) Amortized cost Fair value Due in one year or less $ 21,395 $ 21,605 Due after one year through five years 111,992 116,813 Due after five years through ten years 22,643 23,924 Total held-to-maturity investments $ 156,030 $ 162,342 Actual maturities may differ from contractual maturities because the issuers of certain debt securities have the right to call or prepay their obligations without penalty. We have no significant concentrations of counterparties in our held-to-maturity investment portfolio. Deferred compensation investments and company owned life insurance policies We hold mutual funds, money market funds and company owned life insurance policies to support our deferred compensation liability. Unrealized gains and losses related to these investments still held at September 27, 2020 and September 29, 2019, included in SG&A expense on our Consolidated Statements of Operations and Comprehensive Income (Loss), were as follows: Thirteen weeks ended Thirty-nine weeks ended (in thousands) September 27, September 29, September 27, September 29, Unrealized gains (losses) $ 1,452 $ (115) $ (258) $ 3,078

Amortization expense of our finite-lived intangible assets was $2.0 million and $3.9 million for the thirteen weeks ended September 27, 2020 and September 29, 2019, respectively, and $8.1 million and $13.9 million for the thirty-nine weeks ended September 27, 2020 and September 29, 2019, respectively. Indefinite-lived intangible assets We also held indefinite-lived trade names/trademarks of $6.0 million as of September 27, 2020 and December 29, 2019. Impairments Goodwill We evaluate goodwill for impairment on an annual basis as of the first day of our fiscal second quarter, and whenever events or circumstances make it more likely than not that an impairment may have occurred. These events or circumstances could include a significant change in the business climate, operating performance indicators, competition, client engagement, legal factors, or sale or disposition of a significant portion of a reporting unit. We monitor the existence of potential impairment indicators throughout the fiscal year. Interim impairment test During the first quarter of 2020, the following events made it more likely than not that an impairment had occurred and accordingly, we performed an interim impairment test as of the last day of our fiscal first quarter. We experienced a significant decline in our stock price during the first quarter of 2020. As a result of the decline in stock price, our market capitalization fell significantly below the recorded value of our consolidated net assets. The reduced market capitalization reflected the expected continued weakness in pricing and demand for our staffing services in a volatile economic climate. This was further impacted in March 2020 by COVID-19, which created a sudden global economic shock. We experienced a significant drop in client demand associated with government and societal actions taken to address COVID-19. We expected significant decreases to our revenues and corresponding operating results to continue due to weakness in pricing and demand for our services during the severe economic downturn. While demand was expected to recover in the future, the rate of recovery was expected to vary by geography and industry depending on the economic impact caused by COVID-19 and the rate at which infections would decline to a contained level. Determining the fair value of a reporting unit is judgmental in nature and involves the use of significant estimates and assumptions to evaluate the impact of operating and macroeconomic changes on each reporting unit. The fair value of each reporting unit was estimated using a combination of a discounted cash flow methodology and the market valuation approach using publicly traded company multiples in similar businesses. This analysis required significant judgments, including estimation of future cash flows, which was dependent on internally developed forecasts, estimation of the long-term rate of growth for our business, estimation of the useful life over which cash flows would occur, and determination of our weighted average cost of capital, which was risk-adjusted to reflect the specific risk profile of the reporting unit being tested. The weighted average cost of capital used ranged from 11.5% to 12.0%. The combined fair values for all reporting units were then reconciled to our aggregate market value of our shares of common stock on the date of valuation, while considering a reasonable control premium. As a result of this impairment test, we concluded that the carrying amounts of goodwill for our PeopleScout RPO, PeopleScout MSP and PeopleManagement On-Site reporting units exceeded their implied fair values and we recorded a non-cash impairment loss of $140.5 million, which was included in goodwill and intangible asset impairment charge on our Consolidated Statements of Operations and Comprehensive Income (Loss) for the thirty-nine weeks ended September 27, 2020. The goodwill carrying value of $45.9 million for our PeopleManagement On-Site reporting unit was fully impaired. The goodwill impairment charge for PeopleScout RPO and PeopleScout MSP was $92.2 million and $2.4 million, respectively. Annual impairment test Given the proximity of our interim impairment measurement date (last day of our fiscal first quarter - March 29, 2020) to our annual goodwill impairment measurement date (first day of our fiscal second quarter - March 30, 2020), we performed a qualitative assessment to determine whether it was more likely than not that the fair value of any of our reporting units is less than the carrying value. We considered the current and expected future economic and market conditions surrounding COVID-19 and concluded that it was not more likely than not that the goodwill associated with our reporting units were impaired as of the first day of our fiscal second quarter. Therefore, a quantitative assessment was not performed as of March 30, 2020. Additionally, we did not identify any events or conditions that make it more likely than not that an impairment may have occurred during the period from March 30, 2020 to September 27, 2020. The remaining goodwill balances for PeopleScout RPO and PeopleScout MSP were $22.9 million and $9.7 million , respectively, as of September 27, 2020. Should actual results decline further or longer than we have currently estimated, the remaining goodwill balances may be further impaired. We will continue to closely monitor the operational performance of these reporting units. Finite-lived intangible assets We generally record acquired intangible assets that have finite useful lives, such as client relationships, in connection with business combinations. We review intangible assets that have finite useful lives and other long-lived assets whenever an event or change in circumstances indicates that the carrying value of the asset may not be recoverable. Factors considered important that could result in an impairment review include, but are not limited to, significant underperformance relative to historical or planned operating results or significant changes in business strategies. We estimate the recoverability of these assets by comparing the carrying amount of the asset to the future undiscounted cash flows that we expect the asset to generate. An impairment loss is recognized when the estimated undiscounted cash flows expected to result from the use of the asset plus net proceeds expected from disposition of the asset (if any) are less than the carrying value of the asset. When an impairment loss is recognized, the carrying amount of the asset is reduced to its estimated fair value based on discounted cash flow analysis or other valuation techniques. Interim impairment test With the decrease in demand for our services due to the economic impact caused by the response to COVID-19, we lowered our future expectations, which was the primary trigger of the impairment test as of the last day of our fiscal first quarter for certain of our acquired client relationships intangible assets. As a result of this impairment test, we recorded a non-cash impairment loss for our PeopleScout RPO and PeopleManagement On-Site client relationship intangible assets of $34.7 million, which was included in goodwill and intangible asset impairment charge on our Consolidated Statements of Operations and Comprehensive Income (Loss) for the thirty-nine weeks ended September 27, 2020. The impairment charge for PeopleScout RPO and PeopleManagement On-Site client relationship intangible assets was $25.0 million and $9.7 million, respectively. Considerable management judgment was necessary to determine key assumptions, including projected revenue of acquired clients and an appropriate discount rate of 12.0%. Additionally, we did not identify any events or conditions that make it more likely than not that an impairment may have occurred during the period from March 30, 2020 to September 27, 2020. The remaining client relationship intangible asset balances related to assets impaired for PeopleScout RPO and PeopleManagement On-Site were $5.5 million and $7.6 million, respectively, as of September 27, 2020. Indefinite-lived intangible assets We have indefinite-lived intangible assets related to our Staff Management and PeopleScout trade names. We test our trade names annually for impairment, and when indicators of potential impairment exist. We utilize the relief from royalty method to determine the fair value of each of our trade names. If the carrying value exceeds the fair value, we recognize an impairment loss in an amount equal to the excess, not to exceed the carrying value. Management uses considerable judgment to determine key assumptions, including projected revenue, royalty rates and appropriate discount rates. Interim impairment test We performed an interim impairment test of our indefinite-lived intangible assets as of the last day of our first fiscal quarter for 2020 and determined that the estimated fair values exceeded the carrying amounts for our indefinite-lived trade names. Accordingly, no impairment loss was recognized. Annual impairment test Given the proximity of our interim impairment measurement date (last day of our fiscal first quarter - March 29, 2020) to our annual indefinite-lived trade names impairment measurement date (first day of our fiscal second quarter - March 30, 2020), we performed a qualitative assessment to determine whether it was more likely than not that the fair value of any of our indefinite-lived trade names is less than the carrying value. We concluded that it was not more likely than not that the indefinite-lived intangible assets associated with our Staff Management and PeopleScout trade names were impaired as of the first day of our fiscal second quarter. Therefore, a quantitative assessment was not performed as of March 30, 2020. Additionally, we did not identify any events or conditions that make it more likely than not that an impairment may have occurred during the period from March 30, 2020 to September 27, 2020.

Workers' Compensation Insurance and Reserves [Abstract]
WORKERS' COMPENSATION INSURANCE AND RESERVES	WORKERS’ COMPENSATION INSURANCE AND RESERVES We provide workers’ compensation insurance for our contingent and permanent employees. The majority of our current workers’ compensation insurance policies cover claims for a particular event above a $2.0 million deductible limit, on a “per occurrence” basis. This results in our being substantially self-insured. Our workers’ compensation reserve for claims below the deductible limit is discounted to its estimated net present value using discount rates based on average returns of “risk-free” U.S. Treasury instruments available during the year in which the liability was incurred. The weighted average discount rate was 1.8% and 2.0% at September 27, 2020 and December 29, 2019, respectively. Payments made against self-insured claims are made over a weighted average period of approximately 5 years as of September 27, 2020. The following table presents a reconciliation of the undiscounted workers’ compensation reserve to the discounted workers’ compensation reserve for the periods presented: (in thousands) September 27, December 29, Undiscounted workers’ compensation reserve $ 272,467 $ 274,934 Less discount on workers’ compensation reserve 17,673 19,316 Workers’ compensation reserve, net of discount 254,794 255,618 Less current portion 65,860 73,020 Long-term portion $ 188,934 $ 182,598 Payments made against self-insured claims were $40.6 million and $47.3 million for the thirty-nine weeks ended September 27, 2020 and September 29, 2019, respectively. Our workers’ compensation reserve includes estimated expenses related to claims above our self-insured limits (“excess claims”), and we record a corresponding receivable for the insurance coverage on excess claims based on the contractual policy agreements we have with insurance carriers. We discount this reserve and corresponding receivable to its estimated net present value using the discount rates based on average returns of “risk-free” U.S. Treasury instruments available during the year in which the liability was incurred. At September 27, 2020 and December 29, 2019, the weighted average rate was 1.5% and 2.4%, respectively. The claim payments are made and the corresponding reimbursements from our insurance carriers are received over an estimated weighted average period of approximately 16 years. The discounted workers’ compensation reserve for excess claims was $53.1 million and $45.3 million, and the corresponding gross receivable for the insurance on excess claims was $52.1 million and $45.3 million as of September 27, 2020 and December 29, 2019, respectively. Workers’ compensation cost consists primarily of changes in self-insurance reserves net of changes in discount, monopolistic jurisdictions’ premiums, insurance premiums and other miscellaneous expenses. Workers’ compensation cost of $14.4 million and $18.0 million was recorded in cost of services on our Consolidated Statements of Operations and Comprehensive Income (Loss) for the thirteen weeks ended September 27, 2020 and September 29, 2019, respectively, and $38.0 million and $46.2 million or the thirty-nine weeks ended September 27, 2020 and September 29, 2019, respectively.

Debt Disclosure [Abstract]
LONG-TERM DEBT	LONG-TERM DEBT On March 16, 2020, we entered into a first amendment to our credit agreement with Bank of America, N.A., Wells Fargo Bank, N.A., PNC Bank, N.A., KeyBank, N.A. and HSBC Bank USA, N.A. dated as of July 13, 2018, which extended the maturity of the revolving credit facility established thereunder (the “Revolving Credit Facility”) to March 16, 2025 and modified certain other terms. On June 24, 2020, we entered into a second amendment to our credit agreement (the “Second Amendment”), which modified terms of our financial covenants as well as certain other provisions of the Revolving Credit Facility. The amended credit agreement provides for a revolving line of credit of up to $300.0 million with an option, subject to lender approval, to increase the amount to $450.0 million. Included in the Revolving Credit Facility is a $30.0 million sub-limit for “Swingline” loans and a $125.0 million sub-limit for letters of credit. At September 27, 2020, $1.5 million was drawn on the Revolving Credit Facility as a Swingline loan and $6.1 million was utilized by outstanding standby letters of credit, leaving $292.4 million unused under the Revolving Credit Facility, which is constrained by our most restrictive covenant at this time making $138.5 million available for additional borrowings. At December 29, 2019, $37.1 million was drawn on the Revolving Credit Facility, which included a $17.1 million Swingline loan. Under the terms of the Revolving Credit Facility, we pay a variable rate of interest on funds borrowed under the revolving line of credit in excess of the Swingline loans, based on the London Interbank Offered Rate (“LIBOR”) plus an applicable spread between 1.25% and 3.50%. Alternatively, at our option, we may pay interest based on a base rate plus an applicable spread between 0.25% and 1.50%. The base rate is the greater of the prime rate (as announced by Bank of America), or the federal funds rate plus 0.50%. The applicable spread on LIBOR is 3.50% through the end of fiscal 2020, and will be determined by the consolidated leverage ratio thereafter, as defined in the amended credit agreement. Under the terms of the Revolving Credit Facility, we are required to pay a variable rate of interest on funds borrowed under the Swingline loan based on the base rate plus applicable spread between 0.25% and 1.50%, as described above. At September 27, 2020, the applicable spread on the base rate was 1.50% and the base rate was 3.25%, resulting in an interest rate of 4.75%. A commitment fee between 0.25% and 0.50% is applied against the Revolving Credit Facility’s unused borrowing capacity, with the specific rate determined by the consolidated leverage ratio, as defined in the amended credit agreement. Letters of credit are priced at a margin between 1.00% and 3.25%, plus a fronting fee of 0.50%. Obligations under the Revolving Credit Facility are guaranteed by TrueBlue and material U.S. domestic subsidiaries, and are secured by substantially all of the assets of TrueBlue and material U.S. domestic subsidiaries. The amended credit agreement contains customary representations and warranties, events of default, and affirmative and negative covenants, including, among others, financial covenants. The following financial covenants, as defined in the Second Amendment, are in effect through the second quarter of 2021: • Asset Coverage Ratio of greater than 1.00, defined as the ratio of 60% of accounts receivable to the difference of total debt outstanding and unrestricted cash in excess of $50 million. As of September 27, 2020, our asset coverage ratio was greater than 1.00 at 22.1. • Liquidity greater than $150 million, defined as the sum of unrestricted cash and availability under the aggregate revolving commitments. As of September 27, 2020, our liquidity was greater than the $150 million at $320.6 million. The following financial covenant, as defined in the Second Amendment, will be in effect for the first and second quarter of 2021: • EBITDA, as defined in the amended credit agreement, greater than $12 million for the trailing three quarters ending Q1 2021 and greater than $15 million for the trailing four quarters ending Q2 2021. The following financial covenants, as defined in the Second Amendment, will be in effect starting the third quarter of 2021 and thereafter: • Consolidated leverage ratio greater than 4.00 for the third and fourth quarters of 2021 and greater than 3.00 thereafter, defined as our funded indebtedness divided by trailing twelve months consolidated EBITDA, as defined in the amended credit agreement. • Consolidated fixed charge coverage ratio greater than 1.25, defined as the trailing twelve months bank-adjusted cash flow divided by cash interest expense. As of September 27, 2020, we were in compliance with all effective covenants related to the Revolving Credit Facility.

These fees do not exceed 2.0% of the bond amount, subject to a minimum charge. The terms of these bonds are subject to review and renewal every one to four years and most bonds can be canceled by the sureties with as little as 60 days’ notice. Legal contingencies and developments We are involved in various proceedings arising in the normal course of conducting business. We believe the liabilities included in our financial statements reflect the probable loss that can be reasonably estimated. The amounts recorded are immaterial and resolution of those proceedings are not expected to have a material effect on our results of operations, financial condition or cash flows.

It is our accounting policy to first record these purchases as a reduction to our common stock account. Once the common stock account has been reduced to a nominal balance, remaining purchases are recorded as a reduction to our retained earnings. Furthermore, activity in our common stock account related to stock-based compensation is also recorded to retained earnings until such time as the reduction to retained earnings due to stock repurchases has been recovered. (2) As a result of our adoption of the accounting standard for credit losses, we recognized a cumulative-effect adjustment to retained earnings of $0.6 million in the first quarter of 2020. Share repurchase plan On October 16, 2019, our Board of Directors authorized a $100.0 million share repurchase program of our outstanding common stock. The share repurchase program does not obligate us to acquire any particular amount of common stock and does not have an expiration date. We may choose to purchase shares in the open market, from individual holders, through an accelerated share repurchase program or otherwise. As of September 27, 2020, $66.7 million remains available for repurchase of common stock under the existing authorization. The second amendment to our credit agreement prohibits us from repurchasing shares until July 1, 2021. As part of the existing share repurchase plan, on February 28, 2020 we entered into an accelerated share repurchase (“ASR”) agreement with a third-party financial institution to repurchase $40.0 million of our common stock. Under the ASR agreement, we paid $40.0 million to the financial institution and received an initial delivery of 2,150,538 shares in the first quarter of 2020, which represented 80% of the total shares we expected to receive based on the market price at the time of the initial delivery. This transaction was initiated prior to the medical community’s acknowledgment of the expected severity of the impact COVID-19 would have on the United States.

Income Tax Disclosure [Abstract]
INCOME TAXES	TAXES Our income tax provision or benefit for interim periods is determined using an estimate of our annual effective tax rate, adjusted for discrete items, if any, that are taken into account in the relevant period. Each quarter we update our estimate of the annual effective tax rate, and if our estimated tax rate changes, we make a cumulative adjustment. Our quarterly tax provision and quarterly estimate of our annual effective tax rate are subject to variation due to several factors, including variability in accurately predicting our pre-tax and taxable income and loss by jurisdiction, tax credits, government audit developments, changes in laws, regulations and administrative practices, and relative changes in expenses or losses for which tax benefits are not recognized. Additionally, our effective tax rate can be more or less volatile based on the amount of pre-tax income. For example, the impact of discrete items, tax credits, and non-deductible expenses on our effective tax rate is greater when our pre-tax income is lower. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was enacted in the United States. The CARES Act is an emergency economic aid package to help mitigate the impact of COVID-19. Among other things, the CARES Act provides certain changes to tax laws, including the ability to carry back losses to obtain refunds related to prior year tax returns. Our effective tax rate for the thirty-nine weeks ended September 27, 2020 was 18.7%. The difference between the statutory federal income tax rate of 21% and our effective income tax rate results primarily from a non-deductible goodwill and intangible asset impairment charge and the impact of the CARES Act and the federal Work Opportunity Tax Credit (“WOTC”). WOTC is designed to encourage employers to hire workers from certain targeted groups with higher than average unemployment rates. Other differences between the statutory federal income tax rate result from state and foreign income taxes, certain non-deductible expenses, tax exempt interest, and tax effects of stock-based compensation.

Accounting Policies [Abstract]
Basis of presentation	Financial statement preparation The accompanying unaudited consolidated financial statements (“financial statements”) of TrueBlue, Inc. (the “company,” “TrueBlue,” “we,” “us,” and “our”) are prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and rules and regulations of the Securities and Exchange Commission for interim financial information. Accordingly, certain information and footnote disclosures usually found in financial statements prepared in accordance with U.S. 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. We also considered COVID-19 related impacts to our estimates, as appropriate, within our financial statements and there may be changes to those estimates in future periods. However, we believe that the accounting estimates used are appropriate after considering the increased uncertainties surrounding the severity and duration of COVID-19. These estimates and assumptions are subject to inherent uncertainties, which may result in actual future amounts differing from reported estimated amounts. 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 29, 2019. The results of operations for the thirteen and thirty-nine weeks ended September 27, 2020 are not necessarily indicative of the results expected for the full fiscal year or for any other fiscal period.
Recently adopted accounting standards and recently issued accounting pronouncements not yet adopted	Recently adopted accounting standards Credit losses In June 2016, the Financial Accounting Standards Board issued guidance on accounting for credit losses on financial instruments. This guidance sets forth a current expected credit loss model (“CECL”), which requires the measurement of credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The guidance requires the application of a current expected credit loss model, which is a new impairment model based on expected losses. Under this 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 a loss has been incurred. This guidance was adopted at the beginning of the first quarter of 2020. We were required to apply the new standard by means of a cumulative-effect adjustment to opening retained earnings as of the beginning of the first quarter of 2020. The total impact upon adoption to opening retained earnings was immaterial to both the individual financial assets affected as well as in the aggregate. The following policies have been updated to reflect our adoption of the new standard on accounting for credit losses on financial instruments. Accounts receivable and allowance for credit losses Accounts receivable are recorded at the invoiced amount. We establish an estimate for the allowance for credit losses resulting from the failure of our clients to make required payments by applying an aging schedule to pools of assets with similar risk characteristics. Based on an analysis of the risk characteristics of our clients and associated receivables, we have concluded our pools are as follows: • PeopleReady and Centerline Drivers (“Centerline”) have a large, diverse set of clients, generally with frequent, low dollar invoices due to the daily nature of the work we perform. This results in high turnover in accounts receivable and lower rates of non-payment. • PeopleManagement On-Site has a smaller number of clients, and follows a contractual billing schedule. The invoice amounts are higher than that of PeopleReady and Centerline, with longer payment terms. • PeopleScout has a smaller number of clients, and generally sends invoices on a consolidated basis for a client. Invoice amounts are generally higher for PeopleScout than for PeopleManagement On-Site, with similar payment terms. When specific clients are identified as no longer sharing the same risk profile as their current pool, they are removed from the pool and evaluated separately. The credit loss rates applied to each aging category by pool are based on current collection efforts, historical collection trends, write-off experience, client credit risk, current economic data and forecasted information. The allowance for credit loss is reviewed quarterly and represents our best estimate of the amount of expected credit losses. Each month, past due or delinquent balances are identified based upon a review of aged receivables performed by collections and operations. Past due balances are written off when it is probable the receivable will not be collected. Changes in the allowance for credit losses are recorded in selling, general and administrative (“SG&A”) expense on the Consolidated Statements of Operations and Comprehensive Income (Loss). Due to the uncertain economic environment, it is difficult to estimate the impact caused by COVID–19 on our clients. However, the allowance for credit loss for accounts receivable as of September 27, 2020 is our best estimate of the amount of expected credit losses. Should actual results deviate from what we have currently estimated, our allowance for credit losses could change significantly. The activity related to the allowance for credit losses for accounts receivable during the thirty-nine weeks ended September 27, 2020 was as follows: (in thousands) Beginning balance $ 4,288 Cumulative-effect adjustment (1) 524 Current period provision 6,582 Write-offs (5,925) Foreign currency translation (22) Ending balance $ 5,447 (1) As a result of our adoption of the accounting standard for credit losses, we recognized a cumulative-effect adjustment to our account receivable allowance of $0.5 million as of the beginning of the first quarter of 2020. Restricted cash and investments We establish an allowance for credit loss for our held-to-maturity debt securities using a discounted cash flow method including a probability of default rate based on the issuer’s credit rating. We report the entire change in present value as credit loss expense (or reversal of credit loss expense) in cost of services on the Consolidated Statements of Operations and Comprehensive Income (Loss). The cumulative-effect adjustment to our held-to-maturity debt securities as a result of adopting CECL as of the beginning of the first quarter of 2020 was immaterial, as was the allowance as of September 27, 2020. Workers’ compensation claims reserves We establish an allowance for credit loss for our insurance receivables using a probability of default and losses expected upon default method, with the probability of default rate based on the third-party insurance carrier’s credit rating. Changes in the allowance for credit losses are recorded in cost of services on the Consolidated Statements of Operations and Comprehensive Income (Loss). The cumulative-effect adjustment to our workers’ compensation insurance receivables as a result of adopting CECL as of the beginning of the first quarter of 2020 was immaterial, as was the allowance as of September 27, 2020. Recently issued accounting pronouncements not yet adopted There are no accounting pronouncements which have not yet been adopted that are expected to have a significant impact on our financial statements and related disclosures.

Goodwill and Intangible Assets Disclosure [Abstract]
Intangible Assets, Finite-Lived, Policy	Goodwill We evaluate goodwill for impairment on an annual basis as of the first day of our fiscal second quarter, and whenever events or circumstances make it more likely than not that an impairment may have occurred. These events or circumstances could include a significant change in the business climate, operating performance indicators, competition, client engagement, legal factors, or sale or disposition of a significant portion of a reporting unit. We monitor the existence of potential impairment indicators throughout the fiscal year. Finite-lived intangible assets We generally record acquired intangible assets that have finite useful lives, such as client relationships, in connection with business combinations. We review intangible assets that have finite useful lives and other long-lived assets whenever an event or change in circumstances indicates that the carrying value of the asset may not be recoverable. Factors considered important that could result in an impairment review include, but are not limited to, significant underperformance relative to historical or planned operating results or significant changes in business strategies. We estimate the recoverability of these assets by comparing the carrying amount of the asset to the future undiscounted cash flows that we expect the asset to generate. An impairment loss is recognized when the estimated undiscounted cash flows expected to result from the use of the asset plus net proceeds expected from disposition of the asset (if any) are less than the carrying value of the asset. When an impairment loss is recognized, the carrying amount of the asset is reduced to its estimated fair value based on discounted cash flow analysis or other valuation techniques.
Goodwill and Intangible Assets, Intangible Assets, Indefinite-Lived, Policy	Indefinite-lived intangible assets We have indefinite-lived intangible assets related to our Staff Management and PeopleScout trade names. We test our trade names annually for impairment, and when indicators of potential impairment exist. We utilize the relief from royalty method to determine the fair value of each of our trade names. If the carrying value exceeds the fair value, we recognize an impairment loss in an amount equal to the excess, not to exceed the carrying value. Management uses considerable judgment to determine key assumptions, including projected revenue, royalty rates and appropriate discount rates.

Furthermore, activity in our common stock account related to stock-based compensation is also recorded to retained earnings until such time as the reduction to retained earnings due to stock repurchases has been recovered. (2) As a result of our adoption of the accounting standard for credit losses, we recognized a cumulative-effect adjustment to retained earnings of $0.6 million in the first quarter of 2020.
