In employment discrimination cases in California, you must file a complaint with the DFEH within three (3) years of the date you were harmed (e.g., discriminated against, harassed, or wrongfully terminated). Before filing any employment cases with the court or in arbitration, you must obtain from DFEH a Right-to-Sue notice before filing your own lawsuit. After receiving the Right-to-Sue letter from DFEH, you have one (1) year to file the lawsuit
