If your employer is paying you less due to your sex, race, or ethnicity, you may either: File a claim with the California Labor Commissioner; or File a regular wage and hour lawsuit in court. Filing a wage claim is typically cheaper, easier, and shorter than bringing a lawsuit. All you have to do is complete and email the EPA-1 Form - which asks for basic information about your case - to DLSE2@dir.ca.gov. If you bring a lawsuit, there is a three step process: 1) You have the initial burden of showing that you are getting paid less than a worker of a different sex, race, or ethnicity for substantially similar work. 2) Then your employer has the burden to show that there is a lawful reason for paying you less (such as merit or seniority). 3) If your employer meets this burden, then you have the burden to show that your employer's reason is a pretext for discrimination. If meet this burden, you should win the lawsuit. In any case, it is recommended you consult with an employment lawyer to discuss your options.
