California bars employers from firing or disciplining workers on AI decisions alone
Governor Gavin Newsom signed a package of workplace AI laws, including the No Robo Bosses Act, which from July 2027 requires human review of AI-driven firing and discipline; how courts and regulators will interpret key terms is not yet known.

What happened
- On 30 September, Governor Newsom signed SB 947, the No Robo Bosses Act, and other workplace AI bills.
- From 1 July 2027, SB 947 bars employers from relying solely on an automated decision system to fire or discipline workers, and requires a human to corroborate such decisions.
- AB 1883 limits employer use of AI tools that infer workers' emotions or collect neural data, with some exceptions.
- SB 951 adds AI and automation disclosures to California's layoff-notice rules from 1 January 2027.
Why it matters
California is the largest US state economy, and these are among the first state laws to set rules for how employers use AI in firing, monitoring, and layoffs. Employers elsewhere often adopt California's rules company-wide.
What is confirmed and what is claimed
Confirmed
- Newsom signed SB 947 on 30 September 2026 (Governor's office; state senate press release; CNBC). 12
- SB 947 takes effect on 1 July 2027 (Crowell and Paul Hastings client alerts, based on the bill text).
- AB 1883 restricts AI tools that predict workers' emotional states or collect neural data (Ogletree; Morgan Lewis). 4
- SB 951 requires layoff notices to include information when cuts are substantially due to AI or automation (law-firm summaries, including Morgan Lewis). 4
- Newsom vetoed an earlier version of the No Robo Bosses bill, SB 7, in October 2025 (CNBC). 2
Claimed, not independently verified
- The bill's author and the governor's office describe the package as first-in-the-nation worker protections.
California has become one of the first US states to write specific rules on how employers use AI to manage people. The centerpiece, SB 947, does not ban automated tools in personnel decisions. It says an employer cannot let one make a firing or disciplinary decision on its own: where an automated system is the main basis, a person has to review and corroborate the outcome.
The companion laws reach further into everyday workplace technology. AB 1883 targets monitoring software that claims to read emotions or gathers neural data. SB 951 extends the state's existing layoff-notice law so that employers must say when cuts are substantially due to AI or automation, which could eventually give researchers better data than company press statements provide.
Context
The package is a narrower second attempt. Newsom vetoed a broader No Robo Bosses bill in 2025, and SB 947 is limited mainly to discipline and termination. Colorado and Connecticut have passed their own laws on automated employment decisions, and employment lawyers describe a growing patchwork of state rules. For a wider view of AI regulation, see our AI policy and safety map.
Because AI's effect on jobs is hard to measure, the layoff-notice rule is notable. Today the main count of AI-linked cuts relies on what companies choose to say in announcements; see AI and jobs: how to read the numbers.
What to watch
- Guidance or regulations clarifying what counts as relying "solely" on an automated system.
- The first layoff notices filed under SB 951's AI disclosure rules after 1 January 2027.
- Any legal challenge or federal move to preempt state AI laws.
What we don’t know yet
- How regulators and courts will interpret phrases such as relying "solely" on an automated system, or layoffs "in substantial part" due to AI.
- Exact thresholds and notice periods in the final SB 951 text, which law-firm summaries describe differently depending on the version analyzed.
- How the laws will interact with federal efforts to limit state AI regulation.
