What the Law Does
California Governor Gavin Newsom signed SB 947, the No Robo Bosses Act, on 30 September 2026.
It prohibits employers from using automated decision-making systems as the primary driver of a decision to fire or discipline a worker.
It requires:
- Human review that corroborates automated findings against personnel files, manager evaluations and peer reviews
- Written notice to the affected worker detailing the AI data used in the decision
- A named human contact who can explain the decision
Note the wording: primary driver, not "any use". An employer can still run automated systems over workforce data. It cannot let the output be the thing that ends someone's job without a human having independently checked it.
What Is Not Yet Clear
Reporting has not confirmed the effective date, the penalties, or exactly which employers are covered. Those three things determine whether this has teeth, and we are not going to guess at them. If you have a compliance interest, read the enrolled bill text rather than the coverage, including ours.
The Compromise That Got It Signed
Newsom vetoed an earlier version in October 2025, citing overly broad pre-notification rules.
The version he signed removed the advance notice requirements — and eliminated protections for gig workers.
That second change deserves more attention than it is getting. Algorithmic management is not evenly distributed across the workforce. The people most likely to be hired, scheduled, rated, disciplined and deactivated by software are precisely platform workers. A law restricting AI-driven termination that excludes gig workers protects the employees least exposed to the practice and leaves out the ones most exposed to it.
That is what made it passable. It is also the main limit on what it achieves.
The Timing Is Not a Coincidence Worth Ignoring
On 29 September, the White House directed federal agencies to refer to AI as "super intelligence" and gave the president's science adviser 60 days to draft legislative language defining the term, including whether it should modify, expand or replace existing legal definitions of AI. That clause is widely read as the groundwork for federal preemption of state AI law.
On 30 September, California signed a state AI law anyway.
Whatever else SB 947 is, it is also a jurisdiction legislating into the path of a preemption effort, from the state where most of the companies in question are headquartered. We covered the executive order and the accord here.
The next 60 days decide whether laws like this one survive as written.
What It Means If You Build HR or Workforce Tools
If your product scores, ranks, flags or recommends action on employees, and any customer operates in California, this reaches you — not because the law regulates your software, but because your customers now need things from it:
- An audit trail of what the model saw. The written-notice requirement means the employer has to tell the worker what data drove the decision. If your product cannot produce that, your customer cannot comply.
- A record of human review. Corroboration has to be demonstrable, not asserted.
- Output framed as input, not verdict. A product whose interface presents a conclusion invites exactly the use the law prohibits. One that surfaces evidence a manager weighs does not.
The third point is a design question rather than a legal one, and it is the one worth acting on first.
