- California made a new law about AI and workers.
- Bosses may not punish or fire a worker based only on a computer system.
- A person must check the decision, and the worker must be told in writing.
- The rules start on July 1, 2027.
- Automated decision system
- Software that scores or ranks people to help make decisions about them.
- Corroborate
- To check something against other facts to confirm it is true.
- Civil penalty
- A fine that a company must pay for breaking a rule.
Newsom vetoed an earlier version of the bill a year ago, CalMatters notes. This time unions pushed a slate of AI bills, and the governor signed several of them on the last day to act on bills.
What SB 947 requires
Employers may not rely solely on an automated decision system when they discipline or fire someone. The law covers any system based on machine learning, statistics, data analytics or AI that helps or replaces human judgment.
If an employer relies mainly on such a system, a human must corroborate the result with other information, such as manager evaluations, personnel files, work product or witness interviews. If the result cannot be confirmed, or proves inaccurate, the employer may not use it.
Workers must get a plain-language written notice when they are told of the decision. It must say that a system was mainly relied on and that a human checked it, and it must name a person to contact. Workers can also ask for a description of their own data used by the system.

Enforcement and limits
The state Labor Commissioner and public prosecutors can enforce the law, with a civil penalty of $500 per violation. Retaliation against workers who use these rights is banned.
The rules apply only to discipline and firing, not to hiring. They also cover public employers such as cities and state agencies, and they start on July 1, 2027.
CalMatters reports that the bill was weakened on its way through the legislature and lost an appeals process for workers. “It should be a stronger bill,” said Lorena Gonzalez, who leads the state’s labor federation.
The other bills
Newsom signed 13 bills on September 30 that his office grouped as AI and worker protections. It says they include a requirement to tell workers if a mass layoff, relocation or termination is caused by an AI system, and a ban on surveillance tools in workplace bathrooms.
Other bills deal with AI in health care, deepfakes of people’s likeness, watermarks on AI content, and safety rules for gene synthesis companies.
“AI should expand opportunity – not come at the expense of workers and families,” Newsom said. Senator Jerry McNerney, the author of SB 947, said: “No worker should ever be fired or disciplined by a robo boss.”

California’s new law bars employers from firing or disciplining workers by AI alone, a moderate limit on automated decisions at work. How we rate the mood
The mood shows how the news frames the event for the tech and AI world: as an opportunity (6 and above) or as a loss (below 5). It is not our verdict on who is right.
