Workplace Surveillance Tools: Emotion Recognition and Neural Data
AB 1883 (2025-2026 Regular Session)
Passed the Senate on August 28 and the Assembly on August 30, 2026, and was enrolled to the Governor on September 3, 2026; the Governor's deadline to sign or veto is September 30, 2026. Would add Part 5.8 to Division 2 of the Labor Code to bar employers from using workplace surveillance tools that recognise or predict an employee's emotional state or that collect neural data, enforced by the Labor Commissioner or public prosecutors. Widely reported as signed on September 3; the Legislature's own record shows enrolment on that date, not chaptering, so it is carried here as pending until the Governor acts.
