The Age Discrimination in Employment Act (ADEA) is a federal law that protects workers and job applicants age 40 and over from age-based discrimination in all aspects of employment. The ADEA does not apply to elected officials, independent contractors or military personnel. The law does apply to: Employers with at least 20 employees, Employment agencies, federal government, State and local government (though remedies are often limited), Labor organizations with at least 25 members. In addition, every state has a law that prohibits age discrimination in employment. Most state laws apply to employers with fewer than 20 employees, and often provide stronger protection for older workers than federal law.
