Governor Gavin Newsom signed SB 947, the “No Robo Bosses Act”, on September 30, along with 12 other bills his office grouped as AI and worker protections. From July 1, 2027, California employers may not rely solely on an automated decision system to discipline or fire workers. When such a system was the main basis, a human must corroborate the decision, and the worker must get a written notice.

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.”
