Description of Business [Abstract]
DESCRIPTION OF BUSINESS	DESCRIPTION OF BUSINESS The Company is comprised of the operations, assets, and liabilities of the Company's three regional businesses of Hudson Americas, Hudson Asia Pacific, and Hudson Europe. The Company provides Recruitment Process Outsourcing ("RPO") permanent recruitment and contracting outsourced recruitment solutions. These services are tailored to the individual needs of primarily mid-to-large-cap multinational companies. The Company's RPO delivery teams utilize state-of-the-art recruitment process methodologies and project management expertise in their flexible, turnkey solutions to meet clients' ongoing business needs. The Company's RPO services include complete recruitment outsourcing, project-based outsourcing, contingent workforce solutions, and recruitment consulting. The Company operates directly in ten countries with three reportable geographic business segments: Americas, Asia Pacific, and Europe. See Note 12 for further details regarding the reportable segments. Corporate expenses are reported separately from the reportable segments and pertain to certain functions, such as executive management, corporate governance, human resources, accounting, tax, marketing, information technology, and treasury. A portion of these expenses are attributed to the reportable segments for providing the above services to them and have been allocated to the segments as management service expenses and are included in the segments’ non-operating other income (expense). In December 2019, a novel strain of coronavirus, referred to as COVID-19, was reported to have originated in Wuhan, Hubei Province, China. On January 30, 2020, the World Health Organization (“WHO”) declared that the virus had become a global public-health emergency. On March 11, 2020, the WHO declared the outbreak to be a pandemic, based on the rapid increase in exposure globally. Many countries around the world have imposed quarantines and restrictions on travel and mass gatherings to slow the spread of the virus. Our business continues to be impacted by the outbreak and the accompanying economic downturn. Some of our customers continue to have instituted hiring freezes, while other customers operating in the banking, pharmaceutical and technology industries, which may be considered as essential businesses in different jurisdictions, or customers that are more capable of working remotely than other industries, have been allowed to operate as usual. The inability to conduct in-person interviews has also impacted our business. The expected timeline for this reduction in demand for our services remains uncertain and difficult to predict considering the rapidly evolving landscape. In connection with the COVID-19 pandemic, certain foreign government organizations have begun to offer wage assistance subsidies and tax credits to companies in exchange for maintaining specified levels of compensation and related costs for employees residing in those countries. The Company recognizes the receipt of funds from these organizations in the Other income (expense), net caption on the Condensed Consolidated Statements of Operations. For the three and nine months ended September 30, 2020, the Company received $199 and $464, respectively, related to foreign government assistance, which amounts are included within Other income (expense), net. In the United States, the Company received a $1.3 million loan in connection with the Paycheck Protection Program (“PPP”), administered by the U.S. Small Business Administration (“SBA”), under the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”). All or a portion of the PPP loan may be forgiven by the SBA under certain conditions. Subsequent to the end of the third quarter, the Company applied for loan forgiveness. To the extent that forgiveness is obtained for any portion of the loan in the future, it will be reflected in Other income (expense), net. For more information, see Note 9. On June 10, 2019, the Company announced a reverse stock split of its outstanding shares of common stock, par value $0.001 per share, at a ratio of 1-for-10 (the “Reverse Split”) and that it had filed a Certificate of Amendment of the Company's Amended and Restated Certificate of Incorporation in order to effect the Reverse Split. The filed certificate also reduced the number of authorized shares of common stock to 20 million shares. The Reverse Split and reduction in authorized shares were approved by the Company's Board of Directors (the "Board") on February 25, 2019, and it was approved by the stockholders of the Company at the annual meeting on May 6, 2019. The Board approved the ratio of 1-for-10 on May 24, 2019, and the Reverse Split became effective as of the close of business on June 10, 2019. The Reverse Split had no effect on the par value of the Company's common stock but it reduced the number of issued and outstanding shares of common stock by a factor of 10. Accordingly, the issued and outstanding shares, stock-based compensation disclosures, net loss per share, and other share and per share disclosures for all periods presented have been retrospectively adjusted to reflect the impact of this Reverse Split.
