Whether you are an employee or an independent contractor determines a great deal in the American system, and the label on your paperwork is not decisive.
What turns on it
As an employee you get:
- Minimum wage and overtime protection under the FLSA
- Employer-paid share of FICA payroll taxes
- Access to unemployment insurance
- Workers' compensation coverage
- Anti-discrimination protections in most cases
As a contractor you get none of those by default, and you carry the full self-employment tax burden.
The test is about control
Classification turns on the economic reality of the relationship, not what the contract calls it. Relevant factors include the degree of control the business exercises, whether the work is integral to the business, the permanence of the relationship, and the worker's opportunity for profit or loss.
The Department of Labor has proposed frameworks addressing joint employer status under the FLSA, FMLA and MSPA, distinguishing vertical joint employment — where a worker is employed by a subcontractor or staffing agency but performs work for an intermediary — from horizontal arrangements.
