California is an at-will employment state, meaning that your employer can fire you for just about any reason. But, as discussed above, some terminations are still unlawful and may give you grounds for a wrongful termination claim.
If you believe your employment has been unjustly terminated, you may file a charge of discrimination with either California Civil Rights Department (CRD), or the Equal Employment Opportunity Commission (EEOC), the federal agency in charge of investigating employee complaints.
Once the agency has completed a preliminary investigation of your charge, you will likely be given “a notice of right to sue.” This will allow you to file suit against your employer in court, and give you the green light to hire an attorney to assist you in pursuing compensation from your employer for wrongful termination.
