The Age Discrimination in Employment Act, ADEA of 1967 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. The Act 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. 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.

It shall be unlawful for an employer to discriminate against any of his employees or applicants for employment, for an employment agency to discriminate against any individual, or for a labor organization to discriminate against any member thereof or applicant for membership, because such individual, member or applicant for membership has opposed any practice made unlawful by this section, or because such individual, member or applicant for membership has made a charge, testified, assisted, or participated in any manner in an investigation, proceeding, or litigation under this chapter.
(e) Printing or publication of notice or advertisement indicating preference, limitation, etc.

It shall not be unlawful for an employer, employment agency, or labor organization-
(1) to take any action otherwise prohibited under subsections (a), (b), (c), or (e) of this section where age is a bona fide occupational qualification reasonably necessary to the normal operation of the particular business, or where the differentiation is based on reasonable factors other than age, or where such practices involve an employee in a workplace in a foreign country, and compliance with such subsections would cause such employer, or a corporation controlled by such employer, to violate the laws of the country in which such workplace is located;
(2) to take any action otherwise prohibited under subsection (a), (b), (c), or (e) of this section—
(A) to observe the terms of a bona fide seniority system that is not intended to evade the purposes of this chapter, except that no such seniority system shall require or permit the involuntary retirement of any individual specified by section 631(a) of this title because of the age of such individual; or
(B) to observe the terms of a bona fide employee benefit plan-
(i) where, for each benefit or benefit package, the actual amount of payment made or cost incurred on behalf of an older worker is no less than that made or incurred on behalf of a younger worker, as permissible under section 1625.10, title 29, Code of Federal Regulations (as in effect on June 22, 1989); or
(ii) that is a voluntary early retirement incentive plan consistent with the relevant purpose or purposes of this chapter.

An employer, employment agency, or labor organization acting under subparagraph (A), or under clause (i) or (ii) of subparagraph (B), shall have the burden of proving that such actions are lawful in any civil enforcement proceeding brought under this chapter; or
(3) to discharge or otherwise discipline an individual for good cause.
