California’s Legislature has sent Assembly Bill 1883 to Governor Gavin Newsom, and if he signs it the state will become one of the first to bar employers from using artificial intelligence to read an employee’s emotional state or collect “neural data” gathered by measuring central or peripheral nervous system activity. The bill covers state and local government employers as well as private ones, carves out exceptions for national security, military, and defense related work, and sets a civil penalty of up to $500 per violation, enforceable by the state Labor Commissioner or a public prosecutor.
For HR leaders, the bill lands in the middle of a wave of workplace AI tools that promise to gauge engagement, stress, or attentiveness from facial expression, voice tone, or biometric signals, usually marketed as wellness or productivity features. AB 1883 does not touch AI used in hiring decisions, that fight is already underway in other statutes and cities. It targets a narrower and newer category: AI that infers or measures how a worker feels while they are actually working, whether through a call center sentiment tool or a wearable that tracks nervous system data. Employers already piloting these systems in California, or vendors selling them into the state, now need to budget for a redesign or a shutdown of that specific capability.
The bill’s real signal is where state AI employment law is heading next. Having largely staked out hiring decision AI as the first regulatory target, legislators are now reaching further into the employment relationship, toward the sensors and signals companies use to manage people who are already on the payroll. HR and legal teams that treated AI governance as a hiring only compliance problem should expect emotion and biometric monitoring to be the next line item on that list, in California and, likely, beyond it.
