California now bars AI-only firings. Here's what it means for a contractor's crew discipline, telematics and timekeeping data
California's SB 947 requires a human to corroborate any firing or discipline that primarily rests on an automated system. For contractors with California crews, the exposure is in safety scores, GPS and productivity data.
California has become the first state to bar employers from relying solely on AI to fire or discipline workers. A contractor with California employees now needs a documented human check behind any discipline that started with a telematics score, a GPS flag or a productivity ranking.
What did California actually pass?
Governor Gavin Newsom signed SB 947, the "No Robo Bosses Act," on September 30, per the bill author's office and coverage from The Next Web and UPI. It reverses his veto of a near-identical bill in October 2025. Reporting says it becomes operative July 1, 2027.
The core rules, as reported:
- No AI-only decisions. An employer cannot rely solely on an automated decision system to fire or discipline a worker.
- Human corroboration. When AI output is the primary basis, a person must verify it with other inputs, which the bill lists as managerial evaluations, peer reviews and personnel files.
- Notice. The affected worker gets written notice that AI was used, a description of the employee data it drew on, and a human contact who can explain the decision.
- Enforcement. Crowell's analysis of the bill text says the labor commissioner, attorney general or local prosecutors enforce it, with a $500 civil penalty per violation.
The definition is broad: any computational process built on machine learning, statistical modeling, data analytics or AI that issues scores or recommendations significantly affecting workers.
Where does this touch a construction crew?
The law does not mention construction. The link is an inference from that broad definition. Contractors already run tools that score people:
| Tool | Data it produces | Discipline risk |
|---|---|---|
| Fleet telematics and dashcams | Harsh-braking and speeding scores per driver | Write-ups or terminations based on a score alone |
| Geofenced timekeeping | Late arrivals, off-site clock-ins | Attendance discipline from a GPS flag |
| Jobsite camera safety analytics | PPE or exclusion-zone violations by person | Safety discipline from an unreviewed detection |
| Productivity tracking | Output per labor hour by crew member | Performance terminations from a ranking |
Safety analytics deserve the most care. A flagged violation is a good prompt for a supervisor to look, but a false detection that ends someone's employment is the exact case this law is aimed at.
What should a trade sub or GC do before July 2027?
- Inventory the scoring tools. List every system that rates, flags or ranks individual employees.
- Write a review step. Require a supervisor to look at the underlying video, log or record and add a second input before any discipline.
- Keep the corroboration on file. Note what the human reviewed and why it supported the action.
- Draft the notice. Prepare language for telling a worker AI data was used and who they can call.
- Ask vendors for data descriptions. You will need to say what employee data the system consumed.
- Confirm scope with counsel. Whether a given tool qualifies, and how the final text reads, is a legal question.
Other states have no equivalent yet, and the reporting does not say whether this law reaches subcontractor or union workers differently. Still, a review-before-discipline step is cheap, and it improves defensibility in any state.
The takeaway: if a score alone can end someone's job on your crew, put a person and a second record between the score and the decision.
- What does California's No Robo Bosses Act require of employers?
- SB 947 bars California employers from relying solely on an automated system to fire or discipline a worker. If a decision rests primarily on AI output, a human must corroborate it with other inputs such as managerial evaluations, peer reviews or personnel files.
- When does California's SB 947 take effect?
- Governor Newsom signed it on September 30, 2026, and reporting says it becomes operative on July 1, 2027.
- Does SB 947 apply to telematics or safety-scoring software on construction crews?
- The law's definition covers computational processes built on machine learning, statistical modeling or data analytics that issue scores or recommendations affecting workers. A driver-behavior score or productivity ranking could fall within that language, but a contractor should confirm the fit with employment counsel.
- What must a worker be told if AI was primarily used in a firing?
- Reporting on the law says the worker must get written notice that AI was in the loop, a description of the employee data the system used, and a human contact who can explain the decision.
- What is the penalty for violating SB 947?
- Law-firm analysis of the bill text lists a civil penalty of $500 per violation, enforced by the labor commissioner, the attorney general or local prosecutors. Check the final chaptered text before relying on that figure.
