If you plan to file a lawsuit under federal law alleging discrimination on the basis of race, color, religion, sex (including pregnancy, gender identity, and sexual orientation), national origin, age (40 or older), disability, genetic information, or retaliation, you first have to file a charge with the EEOC (except for lawsuits under the Equal Pay Act).

If you plan to file a lawsuit under the laws in your state, bypassing your state's arbitration process, be sure to consult an attorney.
