Q. "What is age discrimination?"
Answer:
Age discrimination (sometimes called ageism) means treating people less favorably because of their age. In the workplace, this commonly happens when an employer favors a younger worker over an older one. In some cases, age discrimination is unlawful.
If your organization has 20+ employees (for 20+ weeks in the current or previous year), then it is covered by the federal Age Discrimination in Employment Act (ADEA) which forbids age discrimination against people who are 40+. The ADEA requires covered employers to avoid and prevent age discrimination in all aspects including, but not limited to, hiring, work assignments, wages, bonuses, promotions, discipline, and termination.
Many states have age discrimination laws that kick in at a lower employee count and some even protect younger workers. The best way to avoid discrimination is to base employment decisions only on factors that are job-related and irrespective of age.
