California signs new laws restricting how employers can use AI on workers

California Governor Gavin Newsom has signed a suite of new laws aimed at protecting workers from the impacts of artificial intelligence in the workplace, according to the Guardian.

The laws ban employers from relying entirely on AI systems to decide whether to fire a worker, and prohibit using AI to predict employees' emotional states or to collect neural data, meaning information derived from the electrical signals of a person's brain or nerves. The new rules also require companies to notify workers when layoffs are caused by AI, and they prohibit AI-based surveillance in workplace bathrooms.

California, home to many of the world's leading AI companies, is among the first states to roll out workplace regulations specifically targeting the technology's use in employment decisions. The move comes as the federal government has largely taken a hands-off approach to regulating AI, leaving individual states to set their own rules on how the technology can be used in areas such as hiring, firing and workplace monitoring.

Supporters of the new laws argue that as AI tools become more capable of analyzing worker behavior and even biological signals, clear limits are needed to prevent misuse and protect employee privacy and due process. The legislation reflects growing public concern over AI's expanding role in decisions that directly affect people's livelihoods.

The Guardian's report frames California's approach as a potential model for other states as calls for AI workplace regulation grow nationally, though it does not specify an effective date for the new laws or detail enforcement mechanisms.
