California Signed Three Workplace AI Laws: AB 1883, AB 1331, and SB 947 Explained

California’s Governor signed a package of workplace AI bills on September 30, 2026, and the summaries that followed described new notice and consent requirements for employee monitoring. Two of the three bills contain no notice requirement at all. The third contains a notice requirement so specific that it changes the shape of a termination conversation.

Reading the three together tells you which tools in your stack now carry a prohibited use, and which calendar dates to put in front of HR and IT.

AB 1883: Emotion Recognition and Neural Data Become Prohibited Uses

AB 1883 adds Labor Code sections 1580 through 1583. Section 1581(a) prohibits an employer from using an artificial-intelligence-powered workplace surveillance tool for “recognizing, or making inferences or predictions about, an individual’s emotional state,” and for “collecting neural data.”

Two definitions carry the weight. A workplace surveillance tool means a system that collects employee data by means other than direct observation, naming video and audio surveillance, time tracking, geolocation, and electromagnetic tracking. Neural data means information generated by measuring activity of an employee’s central or peripheral nervous system, and not inferred from non-neural sources.

The exception in section 1583 is narrow: use reasonably necessary to comply with federal statutes, regulations, or binding contracts involving aircraft development for the national airspace, or products and services for national security, military, space, or defense purposes.

Penalties reach $500 per violation, enforced by the Labor Commissioner or a public prosecutor, with injunctive relief, punitive damages, and attorney’s fees available.

The practical reach surprises people. Sentiment scoring on recorded support calls infers an emotional state. So does engagement scoring in a video interview platform, a well-being index derived from keystroke cadence, or a coaching tool that flags frustration in a sales call. None of those products markets itself as emotion recognition, and each one performs it. Ask every vendor in your monitoring and enablement stack one question: does any feature infer or predict how an employee feels. The answer belongs in writing.

AB 1331: A Place-Based Ban, Not a Notice Regime

AB 1331 adds Part 5.8 to Division 2 of the Labor Code, sections 1560 through 1565, titled Workplace Surveillance of Employees. Its operative prohibition reads: “Unless directed by a court order, an employer shall not use a workplace surveillance tool to monitor or surveil employees in a bathroom located in the workplace.”

The bill lets employees leave surveillance tools behind when entering a bathroom, except during meal and rest periods required by federal or state law, and permits an employer to check a tool for one-time bathroom entry and exit. It carries the same $500 per violation penalty and the same enforcers.

What it does not carry is a notice or consent requirement. Any compliance plan that reads AB 1331 as a disclosure obligation has built a control the statute never asked for, and has probably skipped the control it did ask for: a configuration review of where location and badge tracking actually reach.

The engineering consequence sits in geofencing precision. A tool that logs presence to a zone rather than to a room cannot prove it stayed out of a bathroom, and a tool that records continuous location on a company device follows the employee everywhere the device goes.

SB 947: Discipline and Termination Need a Human, With Notice

SB 947, the No Robo Bosses Act, becomes operative on July 1, 2027, which makes it the one bill in this package with real runway.

It defines an automated decision system as a computational process derived from machine learning, statistical modeling, data analytics, or artificial intelligence that issues simplified output affecting individuals, excluding spam filters, firewalls, calculators, and databases.

The core rule: employers “shall not rely solely on an ADS when making a disciplinary or termination decision.” Where the employer primarily uses system output, it must “direct a human to corroborate the decision using data…or other relevant corroborating or supporting information.” The act also prohibits using an ADS to prevent compliance with or violate labor, health and safety, employment, or civil rights law, to infer protected status, and to predict and punish workers who exercise legal rights.

The notice provision is the operational one. An employer using an ADS for discipline or termination provides written notice “at the time the employer informs the employee of the decision,” stating that a human reviewed and corroborated the system’s output, and giving contact information for inquiries.

Penalties run $500 per violation, with Labor Commissioner and public-prosecutor enforcement, injunctive relief, punitive damages, and attorney’s fees.

Read that notice timing as a systems requirement rather than an HR template. At the moment a manager delivers a decision, somebody has to produce a written statement that a human corroborated the output. That is an artifact with a timestamp, an author, and a record of what the human looked at, which means the corroboration step has to exist in the workflow before the conversation happens.

What This Package Changes in the Stack

Four moves cover most of the exposure.

Inventory the inference, not the product category. Monitoring, enablement, support quality, and interview tools all score behavior now. Catalog which features produce inferences about emotional state, and which ones feed discipline decisions.

Separate the measurement from the decision. A system that scores activity creates risk when its score routes directly into discipline. Insert the human corroboration step, log it, and keep what the human reviewed.

Fix the retention story for behavioral data. Keystroke, location, and sentiment histories invite both the claim and the discovery request. Decide a window and enforce it.

Put the dates in the compliance calendar. AB 1883 and AB 1331 arrived with the September 30, 2026 signature. SB 947 lands July 1, 2027, and the corroboration-and-notice workflow needs building before it does.

Our AI hiring and automated employment decision guide covers the pre-hire half of this picture, where New York City, Illinois, and Colorado already impose audit and notice duties. This package governs what happens after somebody starts work, and the two sets of obligations meet in the same evidence problem: reconstruct which system produced which output about which person on which date.

Teams whose monitoring surface includes meeting capture should also read our notetaker consent guide, since a transcript of an employee conversation is employee data collected other than by direct observation.

Frequently Asked Questions

Do these laws reach employers headquartered outside California? They attach to the employment relationship and the workplace, so California-based employees bring them into scope wherever the company sits.

Does a sentiment score on a support call count as emotion recognition? Inferring or predicting an emotional state is the prohibited act, and a sentiment score is an inference about an emotional state.

Does AB 1331 require us to notify employees about monitoring? The bill contains no notice requirement. It prohibits bathroom surveillance and sets a $500 per-violation penalty.

Can we still use an automated system to flag attendance problems? Flagging is measurement. SB 947 restricts sole reliance on the system for the disciplinary decision and requires documented human corroboration plus written notice at the time of the decision.

What happens to promotion decisions under SB 947? The act addresses disciplinary and termination decisions. Promotion is not explicitly covered, which does not exempt a promotion system from anti-discrimination law.
