California chaptered three workplace AI statutes on September 30, 2026. HR and ops agents that touch California employees now sit under law, not a bill pile: human corroboration before ADS-primary discipline or termination, AI-cause disclosure on covered WARN notices, and a ban on emotion-inference and neural workplace surveillance.

What Was Signed

Governor Newsom's September 30, 2026 signing post names the triad among same-day worker-protection bills. Chaptered texts:

  • SB 947 (Chapter 859) — Employment: automated decision systems.
  • SB 951 (Chapter 860) — Employment: technological displacement notice.
  • AB 1883 (Chapter 853) — Workplace surveillance tools.

Each was approved by the Governor and filed with the Secretary of State on September 30, 2026.

SB 947 — Human Corroboration Before ADS Discipline

Chaptered Labor Code section 1522 says an employer shall not rely solely on an automated decision system when making a disciplinary or termination decision. If the employer primarily relies on ADS output, a human must corroborate the decision using data used to produce that output or other supporting information (supervisory evaluations, personnel files, work product, peer reviews, witness interviews). If the output cannot be corroborated, or the reviewer finds it inaccurate, incomplete, or misleading, it shall not be used for the decision.

Section 1524 requires a written post-use notice when an employer primarily relied on an ADS for discipline or termination. Section 1526.7 makes the part operative on July 1, 2027.

SB 951 — AI Cause On Covered WARN Notices

Chapter 860 amends the California Worker Adjustment and Retraining Act. When a mass layoff, relocation, or termination is caused in whole or in substantial part by an AI system or other automated technology replacing or automating positions, the notice must add: counts and occupations of those layoffs, the job functions being automated, the category of system, and the statement "This notice is for a technology displacement" at the top.

The chaptered text does not add a delayed-operative section. Under California's default for non-urgency statutes, it takes effect January 1, 2027.

AB 1883 — Emotion And Neural Surveillance

Chaptered Labor Code section 1581 prohibits an employer from using a workplace surveillance tool that uses artificial intelligence to recognize, infer, or predict an individual's emotional state, or to collect neural data. Neural data is defined as information generated by measuring central or peripheral nervous-system activity that is not inferred from non-neural information.

The chaptered text likewise has no delayed-operative section, so the default effective date is January 1, 2027. The statute does not prohibit other workplace surveillance tools that fall outside those two AI uses.

What Operators Should Change

For agents that act on California employment decisions or workplace telemetry:

  • Keep a human in the loop before an ADS is the primary basis for discipline or termination, and emit the written post-use notice.
  • If a covered mass displacement is caused in whole or substantial part by AI or automation, disclose that cause on the WARN notice.
  • Do not point workplace agents at emotion-inference or neural-collection tools.

What The Statutes Do Not Prove

  • These three bills are workplace employment law. They are not the SB 813 / AB 1405 Independent Verification Organization and AI-auditor registry stack signed earlier in September.
  • Newsom's same-day post also lists other worker and consumer bills. This note covers only the SB 947 / SB 951 / AB 1883 triad.
  • Operative dates above are taken from the chaptered texts (SB 947 section 1526.7) and from California's default January 1 effective date where no delayed-operative clause appears.
