You should NOT use this website for legal advice.  We are not lawyers.  But it would be a bad idea to have a whole website devoted to workforce aging issues and not mention discrimination.

This video gives a high-level overview of how the aging of the workforce relates to the Americans with Disabilities Act (ADA) and the Age Discrimination in Employment Act (ADEA).

If you're interested in learning more about age discrimination in the workplace, the agency that enforces age discrimination laws is the US Equal Employment Opportunity Commission, otherwise known as the "EEOC".  Here is a link to their website:
