The ADA is a federal law which is meant to protect individuals with disabilities from employment discrimination, as well as discrimination in other areas of life. The ADA applies to all private employers, state and local governments, employment agencies, and labor unions with 15 or more employees.
Employees age 65 and older may have medical conditions that bring them under the protection of the ADA as individuals with disabilities. If this is true, these employees may request reasonable accommodation for their disability rather than their age.
