Description of Business [Abstract]
DESCRIPTION OF BUSINESS	DESCRIPTION OF BUSINESS The Company delivers Recruitment Process Outsourcing (“RPO”) services consisting of recruitment and contracting solutions tailored to the individual needs of primarily mid-to-large multinational companies. The Company operates directly in fourteen countries with three reportable geographic business segments: the Americas, Asia Pacific, and Europe. The Company’s RPO delivery teams utilize recruitment process methodologies and project management expertise to meet clients’ ongoing business needs. The Company’s RPO services include complete recruitment outsourcing, project-based outsourcing, contingent workforce solutions, and recruitment consulting for clients’ permanent staff hires. Hudson’s RPO services leverage the Company’s consultants, supported by the Company’s specialists, in the delivery of its proprietary methods to identify, select, and engage the best-fit talent for critical client roles. In addition, the Company provides RPO clients with a range of outsourced professional contract staffing services and managed service provider services offered sometimes on a standalone basis and sometimes as part of a blended total talent solution. These services draw upon a combination of specialized recruiting and project management competencies to deliver a wide range of solutions. Hudson RPO-employed professionals - either individually or as a team - are placed with client organizations for a defined period of time based on specific business needs of the client. On March 12, 2024, the Company announced that it entered into a strategic agreement with Executive Solutions, a Dubai-based talent solutions company. This agreement allowed the Company to expand its global footprint and client base in the Middle East market. The Company evaluated the agreement under ASC 805 "Business Combinations" and determined that the transaction did not qualify as either a business combination or an asset purchase. Payments associated with this agreement were classified as compensation expense and were included in the "Salaries and related" caption on the Company's Condensed Consolidated Statements of Operations. In February 2024, Hudson RPO announced an expansion of its service offerings to include executive search in North America, focusing on Life Sciences and Human Resources. This expansion, coupled with the Company’s existing RPO strategy, provides a comprehensive talent acquisition approach, enabling clients to develop streamlined and centralized hiring strategies within a flexible and scalable total talent solution. This service offering better positions the Company as a strategic partner helping clients to implement successful business strategies. On November 15, 2023, Hudson announced the appointment of Jacob “Jake” Zabkowicz as Global Chief Executive Officer of Hudson RPO. Mr. Zabkowicz leads the vision, strategy, and execution of Hudson RPO’s growth plan, while Jeff Eberwein, Chief Executive Officer of Hudson Global, Inc., continues to focus on capital allocation, acquisitions, corporate strategy, and maximizing shareholder value. On October 31, 2023, Hudson completed its acquisition of Hudson Global Resources (Singapore) Pte. Ltd. (“Hudson Singapore”), a provider of recruitment services primarily to clients operating in Singapore. Hudson Singapore has a 30-year track record of senior placements and project recruitment work across Southeast Asia including Singapore, Malaysia, the Philippines, Vietnam, Thailand, and Indonesia.
