California has become the first U.S. state to ban employers from relying solely on artificial intelligence to fire or discipline workers, after Governor Gavin Newsom signed the “No Robo Bosses Act” (SB 947) into law on September 30, 2026.
Key takeaway: Starting July 1, 2027, no algorithm gets the final word on a firing in California. Companies can still use AI tools in HR decisions — but when AI plays a primary role, a human must independently verify the outcome, and the worker must be told AI was involved.
What the law does
Authored by state Senator Jerry McNerney (D-Pleasanton), SB 947 bars California employers from using automated decision-making systems as the sole or primary basis for terminating, disciplining, or demoting a worker. When a company does rely primarily on such a system, a human reviewer must independently corroborate the outcome using sources such as managerial evaluations, peer reviews, and personnel files — not merely rubber-stamp the algorithm’s output. The affected employee must receive written notice that AI factored into the decision, a description of the employee data the system analyzed, and the name of a human contact who can explain it.
How it gets enforced
Enforcement falls to the state labor commissioner, the attorney general, and local prosecutors. Civil penalties can reach $500 per violation, and workers also have a private right of action, with possible punitive damages and attorney’s fees. None of this takes effect immediately: the law becomes operative July 1, 2027, giving employers and HR-software vendors roughly nine months to audit and rebuild their termination workflows.
Why Newsom signed it — after vetoing it last year
The bill is a revival: Newsom vetoed a nearly identical measure, SB 7, in October 2025, writing that it proposed “overly broad restrictions” on how employers use the tools. Nothing about the policy changed much between versions; what changed was the politics, as AI-driven job displacement became one of the defining anxieties of 2026. The law was backed by the California Labor Federation (AFL-CIO) and opposed by the California Chamber of Commerce and business groups. Senator McNerney put the stakes plainly: “No worker should ever be fired or disciplined by a robo boss. Artificial intelligence systems have the potential to increase productivity, but they’ve also been prone to errors, bias, and misjudgments.” Newsom framed the signing as part of a broader state regulatory push, saying, “AI should expand opportunity — not come at the expense of workers and families.”
Part of a bigger package
The No Robo Bosses Act arrived alongside companion bills signed the same day: AB 1883, which prohibits AI tools from predicting employees’ emotional states or collecting neural data, and AB 1331, which bans the use of surveillance tools in restrooms. Taken together, California is drawing a hard line on AI in the workplace that will almost certainly become the template for other states.

When does the No Robo Bosses Act take effect? July 1, 2027.
What must employers tell affected workers? Written notice that AI was used, a description of the employee data the system analyzed, and a human contact who can explain the decision.
