Project Summary: Discussion: Will Age Discrimination Result in Manager Termination? The Age Discrimination Act of 1967 (ADEA) typically applies to employers who have 20 or more employees and protects workers who are 40 years of age and older. Note that in the United States, people under the age of 40 are not in a protected class due to age. With the advancement toward retirement of the baby-boom generation (those people born in 1941 through 1962), the incidences of age discrimination are increasing. Age discrimination can occur when someone is not hired due to being perceived as “too old” to offer long-term benefits to an organization (disparate treatment), or by posting a recruitment notice that “recent high school graduates needed for entry-level positions” stops an entire group of older individuals from having access to a job (disparate impact).
