Employment laws by the number (of employees)
Employers that don’t know which laws apply to them are at greater risk of noncompliance. Which federal employment laws apply to a company depends on how many employees the company has. Some laws apply to employers with only one employee, while others don’t apply unless the employer has 100 or more employees.
Here’s a breakdown of which federal employment laws employers must follow based on the number of employees they have on staff: federal employment laws:
Employers with 1 or more employees must comply with:
- The Employee Polygraph Protection Act
- The Employee Retirement Income Security Act
- The Equal Pay Act
- The Fair Labor Standards Act
- The National Labor Relations Act
- The Occupational Safety and Health Act
- The Uniformed Services Employment and Reemployment Rights Act
- The Family and Medical Leave Act (all public employers)
Employers with 15 or more employees must also comply with:
- The Americans with Disabilities Act
- The Genetic Information Nondiscrimination Act
- The Pregnancy Discrimination Act
- Title VII of the Civil Rights Act of 1964
Employers with 20 or more employees must also comply with:
- The Age Discrimination in Employment Act
Private employers with 50 or more employees must also comply with:
- The Family and Medical Leave Act
Employers with 100 or more employees must also comply with:
- The Worker Adjustment and Retraining and Notification Act
State laws
Those listed are only the federal laws. Each state law has its own definition of which employers are covered.
Key to remember: Employers must be aware of which laws apply to them, and that depends on how many employees they have. Ignorance of the law is no excuse for violations.
