What is Age Discrimination (ADEA)?

Age Discrimination in Employment Act

Quick Answer

Age Discrimination (ADEA) is a law that protects employees and job applicants from discrimination based on their age, specifically those who are 40 years old or older. It prohibits employers from making employment decisions based on age, ensuring fair treatment in hiring, promotions, and other job-related actions.

Overview

The Age Discrimination in Employment Act (ADEA) was enacted to prevent discrimination against older workers. This law makes it illegal for employers to treat employees or job applicants unfairly because of their age. For example, if a company decides not to hire a qualified candidate simply because they are over 50 years old, that could be considered age discrimination under the ADEA. The ADEA applies to employers with 20 or more employees, including state and local governments. It covers various aspects of employment, such as hiring, firing, promotions, and benefits. Employees who believe they have been discriminated against can file a complaint with the Equal Employment Opportunity Commission (EEOC), which investigates claims and can take action if necessary. Understanding the ADEA is important because it helps protect the rights of older workers in a competitive job market. Age discrimination can lead to significant economic disadvantages for individuals and can affect their quality of life. By enforcing the ADEA, the law promotes a diverse workforce and ensures that age does not determine a person's job opportunities.
