Neural data collection and mood-predicting tech face a statewide ban
California is about to tell employers their AI tools cannot read workers' minds - or their moods.
Assembly Bill 1883, which passed both chambers of the state legislature in late August 2026, would bar employers from using AI-powered surveillance tools to collect neural data from employees or to recognize, infer, or predict their emotional states. The bill, authored by Assembly Member Bryan, adds a new Part 5.8 to the California Labor Code. It now sits on the Governor's desk.
The definition of "employer" runs wide. It covers private companies, every level of California government - state agencies, the University of California, charter cities, counties, school districts, transit districts - and labor contractors, including farm and foreign labor contractors.
"Workplace surveillance tool" is equally expansive: any system, application, or device that collects employee data, activities, communications, biometrics, or behaviors by means other than direct observation. Video, audio, geolocation, electromagnetic tracking, and continuous time-tracking tools all fall within the definition.
The bill does not, however, ban all workplace monitoring. It targets AI-driven tools used for two specific purposes - collecting neural data, meaning information generated by measuring the activity of an employee's nervous system, or reading and predicting emotional states. Employers can still deploy AI surveillance for safety, and non-AI monitoring stays untouched.
One narrow exemption applies. Employers operating under federal statutes, regulations, or binding federal contracts tied to aircraft development, national security, military, space, or defense work are carved out - but only for those operations, and only where surveillance is "reasonably necessary" to comply.
On enforcement, the Labor Commissioner and public prosecutors can investigate violations and bring civil actions. Penalties run up to $500 per violation. Courts can also award injunctive relief, punitive damages, and reasonable attorney's fees. The bill does not preempt local ordinances that offer equal or greater protection to workers.
The legislature declared the bill a matter of statewide concern, which means it applies to all cities, including charter cities that might otherwise claim local control.
For HR teams evaluating their tech stack, the compliance question is direct: does any current or planned monitoring tool use AI to gauge how employees are feeling or to capture data from their nervous systems? If the Governor signs, the answer shapes what stays and what goes.
AB 1883 had not been signed into law at the time of this article. Employers should monitor its status and seek legal counsel on compliance timelines once enacted.
