In an effort to counter the expected increase in immigration-related workplace raids, the state Assembly has approved a bill that would require California employers to ask federal immigration agents for a warrant before allowing them access to the workplace. An existing law already requires U.S. Immigration and Customs Enforcement (ICE) to get judicial warrants before conducting a raid, but the new bill seeks to create cover for employees who may be fearful to ask to see documentation. AB 450 also would require employees to ask federal agents for subpoenas before handing over employee personnel records. Employers may also be required to inform their workers about such instances.
