  • Minimum FTE Headcounts?
  • Threshold Number of Employees Needed for Federal Laws?
  • Minimum Thresholds for Federal Employment Laws?
  • When Do Certain Employment Laws Apply?

The number of employees working at your business is a key factor, often overlooked, when understanding federal labor laws.
