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. On October 1, 2020, the Company completed its acquisition of Coit Staffing, Inc., which expanded its presence in the technology sector and established a Technology Group located in San Francisco. In addition to providing RPO services to clients in the tech sector, the Technology Group operates jointly with the Company’s existing teams in the Americas, Asia Pacific, and Europe to provide continuous access to knowledge regarding new and emerging technologies in the RPO, Managed Solutions Provider, and Total Talent Solutions space, enabling the Company to better serve its clients around the world. The Company operates directly in twelve countries with three reportable geographic business segments: Americas, Asia Pacific, and Europe. See Note 13 to the Condensed Consolidated Financial Statements for further details regarding the reportable segments. 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. COVID-19 continues to have an impact around the world and presents risks to the Company, which the Company is unable to fully evaluate or foresee at the current time. However, the Company is vigilantly monitoring the business environment surrounding COVID 19 and continues to proactively address this situation as it evolves. The Company believes it can continue to take appropriate actions to manage the business in this challenging environment due to the flexibility of its workforce and the strength of its balance sheet. In 2020 in connection with the COVID-19 pandemic, certain foreign government organizations offered 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 recognized 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 six months ended June 30, 2020 the Company received $265 related to foreign government assistance, included within Other income (expense), net. In the U.S, the Company received a $1.3 million loan in the second quarter of 2020 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”). The SBA approved the forgiveness of the full amount of the loan on November 30, 2020. For more information, see Note 10.
