Age discrimination involves treating an applicant or employee less favorably because of his or her age. The Age Discrimination in Employment Act (ADEA) forbids age discrimination against people who are age 40 or older. It does not protect workers under the age of 40, although some states have laws that protect younger workers from age discrimination.
Disability discrimination occurs when an employer or other entity covered by the Americans with Disabilities Act, as amended, or the Rehabilitation Act, as amended, treats a qualified individual with a disability who is an employee or applicant unfavorably because she has a disability. Disability discrimination also occurs when a covered employer or other entity treats an applicant or employee less favorably because she has a history of a disability (such as cancer that is controlled or in remission) or because she is believed to have a physical or mental impairment that is not transitory (lasting or expected to last six months or less) and minor (even if she does not have such an impairment).
Pregnancy discrimination involves treating a woman (an applicant or employee) unfavorably because of pregnancy, childbirth, or a medical condition related to pregnancy or childbirth. The Pregnancy Discrimination Act (PDA) forbids discrimination based on pregnancy when it comes to any aspect of employment, including hiring, firing, pay, job assignments, promotions, layoff, training, fringe benefits, such as leave and health insurance, and any other term or condition of employment.
