By California has enacted workplace AI laws limiting how employers use artificial intelligence to monitor, evaluate, and lay off workers, according to HRMorning. Gov. Gavin Newsom signed the measures on Sept. 30, 2026, covering discipline, surveillance, and reductions in force. The package includes SB 947, the “No Robo Bosses” law, AB 1883 on emotion and neural monitoring, AB 1331 on bathroom surveillance, and SB 951 on AI-driven layoffs.
The laws carry civil penalties of $500 per violation under the Labor Commissioner and public prosecutors, with SB 951 adding up to $500 per day and a private right of action under Cal/WARN. For HR leaders, the immediate task is auditing every tool that touches employment decisions.
What each law actually requires
SB 947 prohibits employers from relying solely on an automated decision system, or ADS, to discipline or terminate an employee. An ADS is any tool built on machine learning, statistical modeling, or AI that produces a score, classification, or recommendation used to assist or replace human decisions. If an employer “primarily relies” on ADS output, a person must independently corroborate it using other sources such as supervisor evaluations, personnel files, employee work product, peer reviews, or witness interviews. If corroboration fails, the output cannot be used.
The law requires a written post-use notice when an employer primarily relies on an ADS, and on request, a description of the employee’s own data the system used. It also bars using an ADS to infer protected characteristics or to retaliate.
AB 1883 targets AI-enabled workplace surveillance. Employers may not use such tools to recognize, infer, or predict an employee’s emotional state, or to collect neural data. The law names video or audio surveillance, continuous incremental time-tracking tools, geolocation, electromagnetic tracking, photoelectronic tracking, and photo-optical systems as examples of surveillance that may not be AI-enabled for emotional monitoring. Non-AI monitoring and tools used to ensure safety remain permitted.
AB 1331 bans surveillance tools in workplace bathrooms, with narrow exceptions for court orders, safety cameras, and badge or alarm access with no recording or AI features. Employees may leave tracking devices behind when entering a bathroom.
SB 951 amends Cal/WARN. When a mass layoff, relocation, or termination is caused in whole or in substantial part by AI or automation, the existing 60-day notice must identify the job functions that will be automated and the specific category or type of AI or other automating technology that substantially resulted in the displacement. The notice must state “This notice is for a technology displacement” at the top.
The compliance gaps most HR teams will miss
The term “primarily relies” in SB 947 is not defined in the statute, according to HRMorning, leaving employers to judge when human review is enough. A safer reading is that any disciplinary or termination decision where ADS output is a significant factor, even if a manager signs off, could trigger the corroboration and notice duties. HR teams should document the human review step, the sources used to corroborate, and the final decision rationale.
Vendor contracts are another gap. Many HR, security, and productivity platforms embed AI features employers did not explicitly buy. HRMorning’s practical takeaways include asking vendors in writing what each tool collects and infers. That written record matters because the laws apply to the employer’s use of the tool, not the vendor’s marketing description.
The enforcement structure also creates headcount-based exposure. Penalties are per violation, so a single non-compliant termination could multiply across affected employees. SB 951 adds daily penalties, which accrue quickly for a mass layoff with a defective notice.
What the broader California AI landscape shows
California’s AI bill tracker, as of October 18, 2026, listed 139 AI-related bills, with 83 signed or enacted and 56 dead or vetoed, according to ailawsbystate.com. The next effective date for tracked California AI laws is January 1, 2027. The tracker names workplace-relevant categories including “Workplace surveillance tools” and “Employment: technological displacement: notice,” but does not provide bill numbers or employer duties in its visible text. That makes the HRMorning reporting the more specific source for the four workplace laws.
The tracker also lists the California AI Transparency Act, covering system provenance data, and AI-specific rules for mental health professionals, attorneys, arbitrators, judicial officers, and alternative resolution providers. California ranks fifth among states by number of AI bills tracked.
One inconsistency in the tracker is worth noting. It says “70 days until AB 1979 takes effect” based on an October 18, 2026 update, which would place that date around December 27, 2026. But the same page lists January 1, 2027 as the next effective date. HR teams should confirm each law’s effective date against the chaptered bill text rather than relying on a single tracker.
Practical steps for HR and payroll leaders
HRMorning’s takeaways, from employment attorney Christopher Olmsted of Ogletree Deakins, start with an inventory of every tool, including AI, ADS, and monitoring features embedded in HR, security, and productivity platforms. The next step is determining whether the employer “primarily” relies on an ADS for discipline or termination. Where that is the case, implement human review with a person corroborating the output using independent sources. Prepare notices now, including the post-use notice template for SB 947 and the technology displacement language for SB 951.
Because other states often follow California, HR leaders outside California should treat these laws as a preview of compliance obligations elsewhere. Multistate employers already face a growing list of AI laws, and California is again the testing ground for workplace technology rules.
| Law | Core restriction | Key employer duty | Penalty |
|---|---|---|---|
| SB 947 | No sole reliance on ADS for discipline or termination | Corroborate output, provide post-use notice | $500 per violation |
| AB 1883 | No AI emotion or neural monitoring | Remove AI-enabled emotional inference from surveillance | $500 per violation |
| AB 1331 | No bathroom surveillance | Ensure no recording or AI features in bathroom access | $500 per violation |
| SB 951 | AI-driven layoffs need Cal/WARN disclosure | Identify automated job functions and AI type | Up to $500 per day, private suits |
