If you’re over 40: The Age Discrimination in Employment Act (ADEA) of 1967 protects workers 40 and older. In addition, if you’re in that age category and you’re part of a group layoff, you’re also protected by the Older Workers Benefit Protection Act. This gives you 21 days to consider any severance offer, and another seven days to revoke your agreement.
If you’re part of a minority group: Title VII of the Civil Rights Act of 1964 prohibits companies from making employment decisions based on race/color, religion, s-x, pregnancy or national origin.
If you have a disability: The Americans with Disability Act (ADA) of 1990 prohibits employment discrimination against those with disabilities.
