California signs AI-at-work laws: no firing or discipline by AI alone, disclosure when AI causes mass layoffs, limits on workplace surveillance

California signs AI-at-work laws: no firing or discipline by AI alone, disclosure when AI causes mass layoffs, limits on workplace surveillance

1 October 2026: California's governor, Gavin Newsom, signed a set of artificial-intelligence bills on 30 September 2026. Four of them change what employers in California may do with AI and automated tools at work. The governor's office calls them "first-in-the-nation" worker protections.

Not yet independently verified. SB 947’s 1 July 2027 start date comes from a law firm’s reading of the chaptered bill, not from the governor’s announcement. We have not confirmed the effective dates of SB 951, AB 1331 and AB 1883: law firms disagree on whether the surveillance laws apply immediately or from 1 January 2027, and the notice period under SB 951 is reported differently. We will update this when it can be confirmed, and remove this note.

The four workplace laws

The governor's office lists them as:

• SB 947 (Employment: automated decision systems). "Ensuring real people review automated employment actions by prohibiting employers from only relying on AI when making a disciplinary action or termination decision."
• SB 951 (Employment: technological displacement: notice). "Requiring employers to provide if a mass layoff, relocation, or termination is caused by an AI system." This extends California's layoff-notice regime to say when AI is the cause.
• AB 1331 (Workplace surveillance).
• AB 1883 (Workplace surveillance tools). Among the protections, the announcement names a ban on employers using workplace surveillance tools in a bathroom in the workplace.

The same day the governor signed laws on AI in healthcare decisions, AI transparency and watermarks, digital replicas and deepfakes, and lawyers' use of AI, which this item does not cover.

Update, 5 October 2026: dates and chapter numbers

The bills are now chaptered: AB 1883 as Chapter 853, SB 947 as Chapter 859 and SB 951 as Chapter 860 of the 2026 statutes. According to the employment law firm Ogletree Deakins, SB 947, which it calls the "No Robo Bosses Act", takes effect on 1 July 2027, not on 1 January. It requires a human reviewer to independently corroborate an automated decision system's output before discipline or termination, bars using such a system to infer protected characteristics or to predict and retaliate against workers exercising their rights, and requires notice to workers after use. Ogletree also reports that AB 1883 and AB 1331 carry civil penalties of up to $500 per violation. The start dates of the other three laws have not been confirmed.

Who is affected

Any employer with staff in California, wherever it is based. In practice:

• HR teams using AI or scoring tools in performance management, scheduling, discipline or dismissal decisions;
• employers planning layoffs, who already file state WARN notices and will now have to say whether an AI system caused the cuts;
• vendors of HR, workforce-management and employee-monitoring software selling into California, whose customers will ask for evidence of human review and for configurable monitoring limits.

What to do

• Map where AI touches employment decisions: performance ratings, attendance and productivity flags, scheduling, discipline and termination. For each, make sure a person reviews the decision and that the review is recorded.
• Review monitoring tools against the new surveillance limits, starting with anything that captures audio, video or location in the workplace.
• Update layoff playbooks so that WARN notices can state whether an AI system caused the action.
• Ask your HR software vendors how their products support human review and documentation, and what they are changing for California.
• Read the chaptered bills for the effective dates and exact obligations before changing policy; take legal advice.
