Long-Term Debt [Text Block]	Note F — Long-Term Debt Credit Facility As of June 30, 2023 and December 31, 2022, we had no outstanding borrowings under the New Credit Facility (as defined below). As of June 30, 2023 and December 31, 2022, we had letters of credit outstanding in the amount of $0.8 million. No amounts were drawn against these letters of credit at June 30, 2023. These letters of credit exist to support insurance programs relating to worker’s compensation, automobile, and general liability. As of June 30, 2023, we had the ability to borrow $24.2 million under the New Credit Facility. On December 21, 2021, the Company entered into a new three-year, $25.0 million asset-based revolving credit facility (the "New Credit Facility") with Texas Capital Bank. The Company’s obligations under the New Credit Facility are guaranteed on a joint and several basis by the Company’s material subsidiaries (the “Guarantors”). The New Credit Facility is secured by substantially all of the assets of the Company and the Guarantors pursuant to a Pledge and Security Agreement, dated as of December 21, 2021, among the Company, Texas Capital Bank and the other grantors party thereto (the "Security Agreement"). The New Credit Facility is subject to certain covenants restricting the Company's and its subsidiaries' ability to create, incur, assume or become liable for indebtedness; make certain investments; pay dividends or repurchase the Company's stock; create, incur or assume liens; consummate mergers or acquisitions; liquidate, dissolve, suspend or cease operations; or modify accounting or tax reporting methods (other than as required by U.S. GAAP). The Company was in compliance with all of the requirements as of June 30, 2023. The loans under the New Credit Facility accrue interest at a variable rate equal to the Bloomberg Short-Term Bank Yield Index Rate plus a margin of 2.25% per annum. The interest rate was 6.81% as of June 30, 2023. The outstanding amounts advanced under the New Credit Facility are due and payable in full on December 21, 2024. Unused commitment balances accrued fees at a rate of 0.25%. In connection with entering into the New Credit Facility, the Company and Texas Capital Bank terminated the Old Texas Capital Credit Facility. Prior to termination of the Old Texas Capital Credit Facility, the Company used cash on hand to pay down $12.1 million outstanding under the Old Texas Capital Credit Facility and the remaining $5.0 million of loans outstanding under the Old Texas Capital Credit Facility were deemed to be outstanding under the New Credit Facility. Unlike the Old Texas Capital Credit Facility, Texas Capital Bank did not require the New Credit Facility to be guaranteed by HHS. Cash payments for interest were $29 thousand and $97 thousand for the three months ended June 30, 2023 and 2022, respectively. Cash payments for interest were $167 thousand and $196 thousand for the six months ended June 30, 2023 and 2022, respectively.
