California Governor Gavin Newsom has signed a landmark AI law, SB 947 (dubbed the No Robo Bosses Act), making California the first U.S. state to ban employers from relying solely or primarily on artificial intelligence to make disciplinary or termination decisions. The law requires human review and corroboration using additional information, such as managerial evaluations, for such decisions. Affected employees must also receive written notice that AI was primarily used, a description of the data, and a human point of contact. Newsom had previously vetoed an earlier version of the bill in October, citing concerns about unfocused notification requirements, but signed the revised version after the pre-notification requirement was removed and protections for gig workers were stripped.
