Age Discrimination in Employment Act (ADEA)

It is a federal law prohibiting employment discrimination against individuals 40 or older. The ADEA applies to employers with 20 or more employees and covers various employment practices, including hiring, firing, promotion, compensation, and training. The law also prohibits retaliation against individuals who file complaints or participate in investigations related to age discrimination. The ADEA is enforced by the Equal Employment Opportunity Commission (EEOC).
