The immigration retaliation law is generally enforced by the California Labor Commissioner's Office. Under a 2018 revision to the law, the Labor Commissioner's Office is permitted to investigate suspected violations of the law, even when no employee complaint has been filed. This can happen where the Labor Commissioner becomes suspicious of a violation during investigations. If the Labor Commissioner determines that retaliation has occurred, the office can issue a cease and desist order. This requires the employer to quit the action which violates the law, as well as an order requiring the employer to remedy the situation.
