Age discrimination involves treating someone, either an applicant or employee, less favorably because of his age. The Age Discrimination In Employment Act of 1967 (“ADEA”), as amended, only forbids age discrimination against people of the age of forty or older. It does not protect workers under the age of forty. The law forbids discrimination based upon age when it comes to any aspect of employment, including hiring, firing, compensation, job assignments, promotions, layoffs, job training, fringe benefits, as well as any term or condition of employment. It is not illegal for an employer to favor an older worker over a younger one, even if both workers are over the age of forty. Discrimination can occur when the victim and the person who inflicted the discrimination are both over the age of forty.
