Accounting Policies [Abstract]
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and Cash Equivalents. Cash equivalents consist of liquid investments with an original maturity of three months or less. Cash equivalents are stated at cost, which approximates fair value. The Company maintains cash balances at four major financial institutions in the United States. Accounts are secured by the Federal Deposit Insurance Corporation up to $250,000. The uninsured balances of the Company’s unrestricted cash and cash equivalents accounts aggregated $ 8.6 million as of December 31, 2018 .
Trade and Other Accounts Receivable, Policy [Policy Text Block]	Accounts and Unbilled Receivables. Accounts receivable are uncollateralized customer obligations due under normal trade terms. Customer account balances that are not paid within contract terms are considered delinquent. Accounts receivable are stated at the amount management expects to collect from outstanding balances. The Company maintains an allowance for potential losses primarily based upon management's analysis of delinquent accounts, routine assessment of its customers' financial condition, and any other known factors impacting collectability, including disputed amounts. When management has exhausted all collection efforts, amounts deemed uncollectible are written off. Recoveries of previously written off accounts receivable are recognized in the period in which they are received. The ultimate amount of accounts receivable that becomes uncollectible could differ from management's estimate.
Marketable Securities, Policy [Policy Text Block]	Marketable Securities – Available-for-Sale. Marketable securities are stated at fair value in accordance with the relevant accounting guidance. The Company determines the fair value of its marketable securities using market prices from industry-standard independent data providers. Market prices may be quoted prices in active markets for identical assets (Level 1 inputs) or pricing determined using inputs other than quoted prices that are observable either directly or indirectly (Level 2 inputs), such as yield curve, volatility factors, credit spreads, default rates, loss severity, current market and contractual prices for the underlying instruments or debt, broker and dealer quotes, as well as other relevant economic measures. For periods prior to June 30, 2018, retained mortgage-backed securities were valued at each reporting date using significant unobservable inputs (Level 3 ) by discounting the expected cash flows. An independent valuation specialist was engaged to assist management in estimating cash flows and values for the Company's mortgage securities. It is the Company's responsibility for the overall resulting valuation. During 2018, the Company engaged a broker to market and sell the interest-only and overcollateralization bonds. Through this broker and the subsequent sale of portions of these securities, the Company determined that a market of buyers exists for these securities. As a result, in the second quarter of 2018, the Company reassessed the previous valuation methodology and changed the valuation methodology from a discounted cash flow approach to a market-based approach. The Company determined the market for these securities is not an active market with quotes available to participants, but is instead based on quotes of similar investments. As a result, these investments now qualify as Level 2 investments for reporting purposes. See Note 10 to the consolidated financial statements for additional information on the estimates used in the valuation of our retained mortgage securities.
Goodwill and Intangible Assets, Intangible Assets, Indefinite-Lived, Policy [Policy Text Block]	Goodwill and Indefinite-Lived Intangible Assets. Goodwill and trademarks are assessed annually to determine whether their carrying value exceeds their fair value. In addition, they are tested on an interim basis if an event occurs or circumstances change between annual tests that would more likely than not reduce their fair value below carrying value. If we determine the fair value of goodwill or trademarks is less than their carrying value, an impairment loss is recognized. Impairment losses, if any, are reflected in operating income or loss in the period incurred. The Company performs its annual tests of goodwill and trademarks during the second quarter of each fiscal year.
Intangible Assets, Finite-Lived, Policy [Policy Text Block]	Impairment of Long-Lived Intangible Assets with Finite Lives. Long-lived intangible assets held and used by us which have finite lives are assessed for impairment whenever an event or change in circumstances indicates that the carrying value of the asset may not be fully recoverable. Recoverability is determined based on an estimate of undiscounted future cash flows resulting from the use of an asset and its eventual disposition. An impairment loss is measured by comparing the fair value of the asset to its carrying value. If we determine the fair value of an asset is less than the carrying value, an impairment loss is incurred. Impairment losses, if any, are reflected in operating income or loss in the period incurred.
Revenue from Contract with Customer [Policy Text Block]	Revenue and Cost Recognition - The Company recognizes revenue when control of the promised services is transferred to customers and for the amount that reflects the consideration we are entitled to receive in exchange for those services. Furthermore, revenue is recognized over time based on a fixed amount for each hour of staffing service provided as our customers benefit from our services and as we provide them. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. The Company’s customer contracts have a single performance obligation to transfer the individual goods or services, and it is not separately identifiable from other promises in the contracts and is, therefore, not distinct. Performance obligations are satisfied at the point in time the HCS employees work on behalf of the customer. Contract costs include compensation, benefits and overhead when appropriate. Because of the nature of the contracts and the fact that revenue is earned at the time the employee works for the customer, no contract estimates are necessary.
Income Tax, Policy [Policy Text Block]	Income Taxes. The Company had a gross deferred tax asset of $ 164.0 million and $ 164.7 million as of December 31, 2018 and 2017 , respectively. In determining the amount of deferred tax assets to recognize in the consolidated financial statements, the Company evaluates the likelihood of realizing such benefits in future periods. The income tax guidance requires the recognition of a valuation allowance if it is more likely than not that all or some portion of the deferred tax asset will not be realized. Income tax guidance indicates the more likely than not threshold is a level of likelihood that is more than 50%. Under the income tax guidance, companies are required to identify and consider all available evidence, both positive and negative, in determining whether it is more likely than not that all or some portion of its deferred tax assets will not be realized. Positive evidence includes, but is not limited to the following: cumulative earnings in recent years, earnings expected in future years, excess appreciated asset value over the tax basis and positive industry trends. Negative evidence includes, but is not limited to the following: cumulative losses in recent years, losses expected in future years, a history of operating losses or tax credit carryforwards expiring, and adverse industry trends. The weight given to the potential effect of negative and positive evidence should be commensurate with the extent to which it can be objectively verified. The more negative evidence that exists, the more positive evidence is required to counter to support a conclusion that a valuation allowance is not needed for all or some of the deferred tax assets. Cumulative losses in recent years are significant negative evidence that is difficult to overcome when determining the need for a valuation allowance. Similarly, cumulative earnings in recent years represent significant positive objective evidence. If the weight of the positive evidence is sufficient to support a conclusion that it is more likely than not that a deferred tax asset will be realized, a valuation allowance should not be recorded. The Company examines and weighs all available evidence (both positive and negative and both historical and forecasted) in the process of determining whether it is more likely than not that a deferred tax asset will be realized. The Company considers the relevance of historical and forecasted evidence when there has been a significant change in circumstances. Additionally, the Company evaluates the realization of its recorded deferred tax assets on an interim and annual basis. The Company does not record a full valuation allowance if the weight of the positive evidence exceeds the negative evidence and is sufficient to support a conclusion that it is more likely than not that its deferred tax asset will be realized. If a valuation allowance is necessary, the Company considers all sources of taxable income in determining the amount of valuation allowance to be recorded. Sources of taxable income identified in the income tax guidance include the following: 1 ) taxable income in prior carryback year, 2 ) future reversals of existing taxable temporary differences, 3 ) future taxable income exclusive of reversing temporary differences and carryforwards, and 4 ) tax planning strategies. The Company currently evaluates estimates of uncertainty in income taxes based upon a framework established in the income tax accounting guidance. The guidance prescribes a recognition threshold and measurement standard for the recognition and measurement of tax positions taken or expected to be taken in a tax return. In accordance with the guidance, the Company evaluates whether a tax position will more likely than not be sustained upon examination by the appropriate taxing authority. The Company measures the amount to recognize in its consolidated financial statements as the largest amount that is greater than 50% likely of being realized upon ultimate settlement. The recognition and measurement of tax benefits is often judgmental, and determinations regarding the tax benefit can change as additional developments occur relative to the issue.
Earnings Per Share, Policy [Policy Text Block]	Earnings (Loss) Per Share (“EPS”). Basic EPS excludes dilution and is computed by dividing net income (loss) available to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity. Diluted EPS is calculated assuming all options, nonvested shares and performance-based awards of the Company's common stock have been exercised, unless the exercise would be antidilutive. See Note 11 to the consolidated financial statements for additional details on earnings per share calculation.
New Accounting Pronouncements, Policy [Policy Text Block]	Recently Issued and Adopted Accounting Principles On January 1, 2018, the Company adopted new accounting guidance on revenue recognition prescribed by Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 606, Revenue from Contracts with Customers. We used the modified retrospective approach applied to those customer contracts that were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under the new guidance, while prior periods continue to be reported in accordance with previous accounting guidance. We determined that no cumulative effect adjustment to accumulated deficit was necessary upon adoption as there were no significant revenue recognition differences identified between the new and previous accounting guidance. In April 2015, the FASB issued Accounting Standards Update (ASU) 2015 - 05, Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement , or ASU 2015 - 05. ASU 2015 - 05 amends existing accounting guidance to provide explicit guidance related to a customer’s accounting for fees paid in a cloud computing arrangement. Under the guidance, cloud computing arrangements that include a software license would be accounted for consistent with the acquisition of other software licenses. Conversely, cloud computing arrangements that do not include a software license would be accounted for as a service contract. The Company adopted ASU 2015 - 05 effective January 1, 2018 and there was no impact on the presentation of its results of operations, financial position or disclosures. In June 2018, the FASB issued ASU No. 2018 - 07, Improvements to Nonemployee Share-Based Payment Accounting, which expands the scope of ASC 718, Compensation – Stock Compensation, to include share-based payment transactions for acquiring goods and services from nonemployees and to supersede the guidance in ASC 505 - 50. The new guidance will be substantially the same as current guidance for employee awards. The Company adopted this standard April 1, 2018 and applied it using the modified retrospective approach. The remeasurement of open awards to nonemployees was based on the fair value of such awards as of the date of adoption and resulted in no material change to accumulated deficit or additional paid-in capital. In February 2016, the FASB issued ASU 2016 - 02, Leases (Topic 842 ). This ASU requires lessees to recognize the assets and liabilities that arise from leases on the balance sheet. A lessee should recognize in its balance sheet a liability to make lease payments and an asset representing its right to use the underlying asset for the lease term. This guidance is effective for annual and interim reporting periods beginning after December 15, 2018. The amendments should be applied at the beginning of the earliest period presented using a modified retrospective approach with earlier application permitted as of the beginning of an interim or annual reporting period. The Company estimates adoption of the standard will result in recognition of additional net lease assets and lease liabilities of approximately $0.2 million and $0.2 million, respectively, as of January 1, 2019. The difference between these amounts will be recorded as an adjustment to retained earnings. The Company does not believe the standard will materially affect our consolidated net earnings. In August 2018, the SEC adopted the final rule under SEC Release No. 33 - 10532, Disclosure Update and Simplification, amending certain disclosure requirements that were redundant, duplicative, overlapping, outdated or superseded. In addition, the amendments expanded the disclosure requirements on the analysis of stockholders' equity for interim financial statements. Under the amendments, an analysis of changes in each caption of stockholders' equity presented in the balance sheet must be provided in a note or separate statement. The analysis should present a reconciliation of the beginning balance to the ending balance of each period for which a statement of operations and comprehensive income (loss) is required to be filed. The Company anticipates its first presentation of year-to-date quarterly changes in shareholders' deficit will be included in its Form 10 -Q for the quarter ending March 31, 2019.
