Olsten Staffing Services, founded in 1950 by William Olsten, was a major American temporary staffing agency. It grew to become one of the largest staffing firms globally, offering a wide range of services including temporary and permanent placement, professional staffing, and managed services across various sectors like office administration, light industrial, healthcare (Olsten Health Services), and information technology. In a landmark deal within the staffing industry, Olsten Corporation was acquired by Adecco S.A. in March 2000 for approximately $1.6 billion. This acquisition significantly expanded Adecco's footprint in North America. While the Olsten brand has largely been integrated into Adecco, its legacy contributed to shaping the modern staffing industry.
The Melville headquarters served as the central command for Olsten's extensive national and international operations, overseeing strategy, finance, marketing, and branch network management.
Likely a substantial corporate office facility designed to accommodate a large administrative and executive staff, characteristic of a leading publicly traded company of its time. Specific architectural details are not widely publicized post-acquisition.
The work culture at Olsten's HQ would have been dynamic and performance-driven, typical of a large sales and service organization in the competitive staffing industry. It would have emphasized customer service, rapid response to client needs, and efficient management of a large temporary workforce.
The Melville HQ was significant as the nerve center of one of the world's largest staffing organizations, dictating policies and strategies that impacted thousands of employees and clients globally.
Prior to its acquisition by Adecco in 2000, Olsten Staffing Services had established a significant international presence, with offices and operations in North America (USA, Canada, Mexico) and Europe (e.g., UK, France, Germany). These international branches supported multinational clients and sourced talent globally. These operations are now part of Adecco Group's extensive global network.
