California Gov. Gavin Newsom has signed a suite of new laws that sharply restrict how employers can use artificial intelligence against their own workers, banning companies from relying entirely on AI to decide who gets fired, from using the technology to predict employees' emotional states, and from collecting neural data such as electrical signals from a person's brain or nerves.
The package, signed Thursday according to an analysis published by The Guardian, also requires companies to notify workers when layoffs were caused by AI and prohibits AI surveillance in workplace bathrooms. Taken together, the laws amount to one of the most sweeping state-level responses yet to the use of AI in employment decisions — passed in the state that is home to many of the companies building the technology. For more context on this story, see our ongoing AI news.
What the New Laws Do
The provisions target the moments where workers have the least power. Under the new rules, an employer can no longer lean solely on an AI system to make a termination decision, and workers must be told when artificial intelligence played a role in their layoff. Emotional-state inference — software that claims to read whether an employee is frustrated, distracted or disengaged — is now off-limits, as is the collection of neural data from workers' brains and nervous systems.
The laws also draw a hard line around physical privacy, prohibiting AI-powered surveillance in workplace bathrooms entirely.
The layoff-notification requirement may prove the most consequential in practice: reductions driven partly by AI automation can no longer be presented as ordinary restructuring without disclosing the technology's role in the decision.
Why Lawmakers Moved Now
The regulatory shift arrives as workers increasingly worry that AI will take their jobs, fuel discriminatory decisions and expand workplace surveillance. Unions and worker advocates pushed hard for the rules, and The Guardian's reporting points to practices that alarmed them: heat maps that track employees' movements, including how long they spend in the bathroom, and automated systems that score workers' tone of voice. Amazon warehouse workers have previously complained about being timed on bathroom breaks, and nurses at Kaiser Permanente have said automated systems rated their tone of voice in patient interactions.
The backdrop is record AI spending at major technology companies alongside waves of job cuts. In June, Meta paused a program that tracked workers' computer activity to train its AI models, and a month later dozens of employees filed a lawsuit claiming the company's AI tools targeted workers with disability accommodations or those on medical or parental leave for layoffs.
Labor Leaders Call It a Turning Point
Lorena Gonzalez, president of the California Federation of Labor Unions, AFL-CIO, who has been helping leaders in other states draft similar regulations, told The Guardian the moment is a milestone for organized labor.
"It's a turning point," Gonzalez said. "It's really the first time we're seeing California workers showing the country that we don't have to accept [this]."
She noted that companies' own product catalogs are a roadmap for what may already be in use on shop floors and in offices: "If it's being sold, that's a good indication" it could be deployed. The federation plans to use the momentum from the new laws to revive a requirement that employers disclose when they are using AI in the workplace — a bill that died in the state Assembly's appropriations committee earlier this year.
The Enforcement Gap
The statutes are not without limits. Robin Feldman, director and founder of the AI Law & Innovation Institute at the University of California College of the Law, San Francisco, told The Guardian that the new laws lack a private right of action.
"The bills have no private enforcement," Feldman said. "In other words: workers can't sue. Only the government can enforce the laws."
That structure puts the burden on California's labor and civil rights agencies to investigate and prosecute violations, which worker advocates say will test whether the laws have teeth in practice. Without lawsuits from affected employees, enforcement will depend on agency priorities, staffing and complaints from workers willing to come forward.
What Comes Next
California is not alone, but it is ahead. Colorado, Connecticut, Illinois and Texas have passed narrower AI-in-the-workplace laws, and Gonzalez said more bills are being lined up across the country, with California's package likely to serve as a template.
The package also builds on an active year for AI legislation in Sacramento. Newsom has already signed bills requiring independent audits of frontier AI developers and mandating disclosure when AI-generated performers appear in advertising, and the workplace package extends that regulatory posture from labs and campaign ads into the day-to-day mechanics of employment. With the federal government keeping a hands-off posture on AI regulation, states — not Washington — are becoming the primary arena where the rules for AI at work are being written.
For employers, the message is that AI-driven HR decisions will now face legal scrutiny in the country's largest state labor market. For workers, it is the first clear signal that the algorithmic management tools arriving in workplaces come with limits — at least in California.
