The EEOC is the federal agency that enforces federal laws against employment discrimination. The EEOC enforces the laws that protect you if you have been discriminated against or harassed at work because of your race, color, religion, sex (including pregnancy, gender identity, and sexual orientation), national origin, disability, age (age 40 or older) or genetic information. The EEOC also enforces the law that prohibits employers from retaliating against a worker because the worker made a complaint or helped another worker complain about job discrimination or harassment.
Some states also have agencies where you can file. You find out about state agencies here: https://www.eeoc.gov/field-office.
If you think you have been discriminated against by your employer, you can contact the EEOC for information about how the agency can help.
For some laws, you must file a charge with the EEOC before you can go to court to hold your employer
