Master the Staffing Industry
Your comprehensive guide to understanding staffing, talent acquisition, and contingent workforce management — from bill rates and SLAs to MSPs, VMSs, and everything in between.
What Is the Staffing Industry?
The staffing industry connects organizations with talent — from temporary workers filling seasonal gaps to highly specialized consultants driving transformation.
It's a complex ecosystem involving multiple players: staffing suppliers, Managed Service Providers (MSPs), Vendor Management Systems (VMS), Recruitment Process Outsourcing (RPO) firms, and the clients who need talent. Understanding how these pieces fit together is critical for anyone entering this space.
The industry generates over $500 billion globally, with the U.S. alone accounting for roughly $220 billion. It touches every sector — healthcare, technology, manufacturing, finance, and more. Source: SIA Global Staffing Report
