Each year Staffing Industry Analysts produces the list of the Best Staffing Firms to Work For with research firm Quantum Workplace.

This year, the Best Staffing Firms to Work For North America winners are categorized by number of internal employees into five size groups, with grand prize winners in each group followed by a list of other firms on the list in alphabetical order. In addition, there are two UK categories: 10 to 50 internal employees and 51-plus internal employees, with a grand prize winner in each. There is also a category for “Best Staffing Firms to Temp For” in North America. For this contest (for external workers), there was a top winner, but all firms with a Net Promoter Score of 50 or more were finalist winners.

The winners were initially announced at SIA Executive Forum North America held earlier this year in Miami Beach, Fla. The competition was sponsored by Monster Worldwide, Inc.
