Age discrimination involves treating someone (an applicant or employee) less favorably because of his age.
The Age Discrimination in Employment Act (ADEA) only forbids age discrimination against people who are age 40 or older. It does not protect workers under the age of 40, although some states do have laws that protect younger workers from age discrimination.
It is not illegal for an employer or other covered entity to favor an older worker over a younger one, even if both workers are age 40 or older.
Discrimination can occur when the victim and the person who inflicted the discrimination are both over 40.
The law forbids discrimination when it comes to any aspect of employment, including hiring, firing, pay, job assignments, promotions, layoff, training, fringe benefits, and any other term or condition of employment.
It is unlawful to harass a person because of his or her age.
Harassment can include, for example, offensive remarks about a person's age. Although the law doesn't prohibit simple teasing, offhand comments, or isolated incidents that aren't very serious, harassment is illegal when it is so frequent or severe that it creates a hostile or offensive work environment or when it results in an adverse employment decision (such as the victim being fired or demoted).
The harasser can be the victim's supervisor, a supervisor in another area, a co-worker, or someone who is not an employee of the employer, such as a client or customer.
An employment policy or practice that applies to everyone, regardless of age, can be illegal if it has a negative impact on applicants or employees age 40 or older and is not based on a reasonable factor other than age.
