Accounting Policies [Abstract]
Basis for presentation	Basis for presentation. These interim condensed consolidated financial statements are unaudited, but in the opinion of our management, reflect all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of results for such periods. The condensed consolidated balance sheet at December 31, 2019 is derived from the December 31, 2019 audited consolidated financial statements. The results of operations for any interim period are not necessarily indicative of results for the full year. Certain disclosures have been condensed or omitted from the interim financial statements included in this report. Therefore, these financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in our Annual Report on Form 10-K for the year ended December 31, 2019 filed with the Securities and Exchange Commission on March 16, 2020 (“the 2019 Form 10-K”).
Use of estimates	Use of estimates. Our accounting policies conform to Generally Accepted Accounting Principles in the United States (“GAAP”). The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and judgments that affect our reported financial position and results of operations. We review significant estimates and judgments affecting our consolidated financial statements on a recurring basis and record the effect of any necessary adjustments prior to their publication. Estimates and judgments are based on information available at the time such estimates and judgments are made. Adjustments made with respect to the use of these estimates and judgments often relate to information not previously available. Uncertainties with respect to such estimates and judgments are inherent in the preparation of financial statements. Estimates and judgments are used in, among other things, (1) aspects of revenue recognition, (2) valuation of acquisition related tangible and intangible assets and assessments of all long-lived assets for possible impairment, (3) estimating various factors used to accrue liabilities for workers’ compensation, auto, medical and general liability, (4) establishing an allowance for uncollectible accounts receivable, (5) estimating the useful lives of our assets, (6) assessing future tax exposure and the realization of tax assets, (7) selecting assumptions used in the measurement of costs and liabilities associated with defined benefit pension plans and (8) managing our foreign currency risk with certain debt obligations associated with net investments in foreign operations.
Fair value of financial instruments	Fair value of financial instruments. Our financial instruments consist primarily of cash, cash equivalents, accounts receivable, accounts payable and debt obligations. The carrying amount of cash, cash equivalents, accounts receivable and accounts payable are representative of their respective fair values due to the short-term maturity of these instruments. The fair value of our banking facility is representative of the carrying value based upon the variable terms and management’s opinion that the current rates available to us with the same maturity and security structure are equivalent to that of the banking facility.
Concentration of credit risk	Concentration of credit risk. No single customer accounts for more than 10% of consolidated revenues.
Earnings (loss) per share	Earnings (loss) per share. Basic earnings (loss) per share is computed by dividing net income (loss) available to Team shareholders by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings (loss) per share is computed by dividing net income (loss) available to Team shareholders by the sum of (1) the weighted-average number of shares of common stock outstanding during the period, (2) the dilutive effect of the assumed exercise of share-based compensation using the treasury stock method and (3) the dilutive effect of the assumed conversion of our convertible senior notes under the treasury stock method. Our intent is to settle the principal amount of the convertible senior notes in cash upon conversion. If the conversion value exceeds the principal amount, we may elect to deliver shares of our common stock with respect to the remainder of our conversion obligation in excess of the aggregate principal amount (the “conversion spread”). Accordingly, the conversion spread is included in the denominator for the computation of diluted earnings per common share using the treasury stock method.
Reclassifications	Reclassifications. Certain amounts in prior periods have been reclassified to conform to the current year presentation. Such reclassifications did not have any effect on our financial condition or results of operations as previously reported.
Newly Adopted Accounting Principles	Newly Adopted Accounting Principles Topic 326 - Credit Losses. In June 2016, the FASB issued Accounting Standard Update (“ASU”) No. 2016-13, Financial Instruments-Credit Losses, which established ASC Topic 326, Credit Losses (“ASC 326”). Along with subsequent ASUs to clarify certain provisions, ASC 326 introduced a new impairment model for financial instruments that is based on expected credit losses rather than incurred credit losses. The new impairment model applies to most financial assets measured at amortized cost, including trade accounts receivable. We adopted ASC 326 using the modified retrospective method for all financial assets measured at amortized cost. Results for reporting periods beginning after January 1, 2020 are presented under ASC 326 while prior period amounts are reported in accordance with previously applicable GAAP based on incurred credit losses. The cumulative effect of our adoption of ASC 326 on January 1, 2020 resulted in a $1.0 million decrease, net of tax, to beginning retained earnings on our consolidated balance sheet. Refer to Note 3 for further discussion of ASC 326. ASU No. 2018-15. In August 2018, the FASB issued ASU No. 2018-15, Intangibles – Goodwill and Other – Internal-Use Software (Topic 350): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (“ASU 2018-15”), that requires implementation costs incurred in cloud computing arrangements to be deferred and recognized over the term of the arrangement, if those costs would be capitalized in a software licensing arrangement under the internal-use software guidance in Topic 350. ASU 2018-15 requires an entity to disclose the nature of its hosting arrangements that are service contracts and provide disclosures as if the deferred implementation costs were a separate, major depreciable asset class. Our adoption of ASU No. 2018-15 as of January 1, 2020 resulted in a reduction of $4.9 million from property, plant, and equipment with $0.9 million reclassified to other current assets and $4.0 million reclassified to other non-current assets on our consolidated balance sheet. Accounting Principles Not Yet Adopted ASU No. 2019-12. In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740) Simplifying the Accounting for Income Taxes, that simplifies the accounting for income taxes by eliminating some exceptions to the general approach in ASC 740, Income Taxes as well as clarifies aspects of existing guidance to promote more consistent application. ASU 2019-12 clarifies and amends existing guidance related to intraperiod tax allocation and calculations, recognition of deferred taxes for change in ownership group, evaluation of a step-up in the tax basis of goodwill and other clarifications. We are currently evaluating the impact this ASU will have on our financial statements and we plan to adopt it as of January 1, 2021. ASU No. 2020-04. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The guidance provides optional expedients and exceptions for applying GAAP to contract modifications and hedging relationships, subject to meeting certain criteria that reference LIBOR or another rate that is expected to be discontinued. The amendments in ASU 2020-04 are effective for all entities as of March 12, 2020 through December 31, 2022. We are currently determining whether we will elect the optional expedients as well as evaluating the impact of this guidance on our consolidated financial position, results of operations, and cash flows. ASU No. 2020-06. In August 2020, the FASB issued ASU 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, which simplifies the accounting for convertible instruments by eliminating certain separation models and will generally be reported as a single liability at its amortized cost. In addition, ASU 2020-06 eliminates the treasury stock method to calculate diluted earnings per share for convertible instruments and requires the use of the if-converted method. The amendments in ASU 2020-06 are effective for this Company as of January 1, 2022 with the option to early adopt as of January 1, 2021. We are currently determining when we will elect to adopt as well as the impact this ASU will have on our financial statements.
