Age discrimination is present if an individual covered under this provision is treated unfavorably in the terms and conditions of his/her employment because of his or her age.
Federally, the Age Discrimination in Employment Act only protects employees over the age of 40 from age discrimination – moreover, you cannot sue under the ADEA if your workplace employs less than 20 people.
However, age discrimination is permitted in certain, special circumstances. For instance, executives who make over $44,000 annually can be forced to retire at the age of 65, and certain government workers (such as fire personnel, police officers, or air traffic controllers) are also subject to certain age limitations.
If you feel you have been subject to age discrimination, you should file a claim with the Equal Employment Opportunity Commission or under your state discrimination laws.
