Yes, in many cases you can sue your employer for age discrimination, but there is an important catch: under federal law you almost always have to file a charge with the U.S. Equal Employment Opportunity Commission (EEOC) before you can take your employer to court. The main federal law is the Age Discrimination in Employment Act (ADEA), and it protects workers who are 40 years old or older. This article walks through who is covered, what counts as illegal age discrimination, the deadlines that actually exist, and the practical steps to protect your rights.
The Federal Baseline: The ADEA
The Age Discrimination in Employment Act of 1967 is the primary federal law on age discrimination. It is enforced by the EEOC. The ADEA makes it illegal for covered employers to treat workers age 40 and over worse because of their age in any aspect of employment, including hiring, firing, layoffs, pay, promotions, job assignments, training, and benefits.
A few key points about how the ADEA works:
- It covers workers 40 and older. The ADEA does not protect younger workers from being treated worse than older workers. It is a one-way protection for the 40-and-up group.
- It applies to employers with 20 or more employees. It also covers labor unions, employment agencies, and federal, state, and local governments. Smaller employers may not be covered by the ADEA, but state law often fills that gap (more on that below).
- It bans both intentional discrimination and certain neutral policies. An obvious example is firing someone and saying they are "too old" or replacing them with a younger worker to "freshen up the team." But a policy that looks age-neutral on its face can also be illegal if it disproportionately harms older workers and is not based on a reasonable factor other than age.
What Counts as Age Discrimination?
Illegal age discrimination is more than just rude comments. It generally means an employer took a negative job action against you because of your age. Common examples include:
- Being fired or laid off and replaced by a significantly younger worker, especially someone with similar or weaker qualifications.
- Being passed over for a promotion that goes to a younger, less-experienced employee.
- Layoffs or "reductions in force" that fall heavily on older workers while younger workers in similar roles are kept.
- Being pushed toward early retirement, or pressured with comments like "don't you want to slow down?" or "we need new energy."
- Job postings or recruiting aimed at "digital natives," "recent grads," or "young, energetic" candidates.
- Harassment so frequent or severe that it creates a hostile work environment based on age.
Age-related comments by managers, especially decision-makers, can be powerful evidence. Phrases like "old-timer," "set in your ways," "overqualified," or "not a culture fit" can be code for age bias, particularly when paired with a negative job action.
What You Have to Prove
The ADEA has a tougher standard of proof than some other discrimination laws. Under U.S. Supreme Court rulings, an employee generally must show that age was the "but-for" cause of the employer's decision, meaning the harmful action would not have happened but for your age. Age does not have to be the only reason, but it has to be the deciding factor. This is a key reason these cases benefit from good documentation and, often, a lawyer's help.
The Step You Cannot Skip: Filing an EEOC Charge
Here is the part that surprises many people. You usually cannot walk straight into federal court with an ADEA claim. First you must file a Charge of Discrimination with the EEOC (or, in some situations, a state or local fair-employment agency). This is a required step that preserves your right to sue.
Deadlines matter enormously here:
- The basic federal deadline to file an EEOC charge is 180 days from the date the discrimination happened (for example, the day you were fired or told of the layoff).
- That deadline extends to 300 days if your state has its own age-discrimination law and a state or local agency that enforces it, which most states do. Because this varies by state, do not assume which deadline applies to you. When in doubt, treat the 180-day clock as your safe deadline and act early.
Missing the charge-filing deadline can permanently end your ability to sue, so this is the single most time-sensitive thing to get right. You do not need a lawyer to file a charge, and you can start the process through the EEOC's public portal, by phone, or at a field office.
Note that the ADEA has one wrinkle that differs from race or sex discrimination claims: for age cases, you generally do not have to wait to receive a "Notice of Right to Sue" before going to court. You can file an ADEA lawsuit once at least 60 days have passed since you filed your charge, even if the EEOC has not finished. Still, filing the charge itself remains mandatory.
Where State Law Adds Stronger Protections
Federal law is the floor, not the ceiling. Many states have their own age-discrimination laws that go further than the ADEA. Depending on where you work, state law may:
