California SB 951: AI-Displacement Disclosures Join the Cal-WARN Notice on January 1, 2027
BREAKING NEWS
October 13, 2026
California Senate Bill 951 adds technology-displacement disclosures to certain notices under the California Worker Adjustment and Retraining Notification Act, known as Cal-WARN. The new requirements take effect January 1, 2027.
For covered actions substantially caused by artificial intelligence or other automated technology, the notice must now disclose specified workforce and technology details. Cal-WARN compliance will therefore depend on both notice timing and notice content.
What SB 951 changes
SB 951, Chapter 860, requires additional content in a Cal-WARN notice when a covered mass layoff, relocation, or termination is caused in whole or in substantial part by an AI system or other automated technology replacing or automating employment positions.
The additional notice elements are:
- The number, classification or occupation, and work location of affected layoffs.
- The job functions performed by replaced workers that will be automated.
- The specific category or type of AI system or other automating technology substantially responsible.
- This statement at the top of the notice: "This notice is for a technology displacement."
The requirements are in the chaptered text of SB 951, which amends Labor Code sections 1400.5 and 1401. The Governor's September 30 signing announcement also identifies SB 951 as legislation concerning technological displacement notices.
When Cal-WARN applies
SB 951 adds notice content. It does not replace Cal-WARN's existing coverage rules or advance-notice framework.
Under California Labor Code section 1400.5, a covered establishment generally employs, or employed during the preceding 12 months, 75 or more persons. A mass layoff is defined as a layoff of 50 or more employees at a covered establishment during a 30-day period.
The statute separately defines relocation and termination. The 50-employee threshold applies to the definition of mass layoff and should not be treated as a universal threshold for every covered action. Organizations should assess each event against the statutory definitions and circumstances.
For covered actions, Labor Code section 1401 generally requires written notice 60 days before the order takes effect. Required recipients include affected employees, the Employment Development Department (EDD), the local workforce development board, and applicable local officials. Exceptions and other statutory conditions require separate review.
The California Labor Commissioner's Cal-WARN guidance summarizes the existing notice framework and remedies. SB 951 does not create a general notice requirement for every AI deployment, hiring change, or job-function redesign. The new disclosures apply when the event is a covered Cal-WARN action and meets the statute's technology-displacement condition.
Why notice content now needs its own control
A notice can meet its deadline and still omit required information. SB 951 makes the accuracy and completeness of the AI-displacement disclosures a distinct compliance obligation.
Organizations should register each element separately. Assign an accountable owner for workforce counts and classifications, work locations, affected job functions, and the technology category. Identify who determines whether automation caused the covered action in whole or in substantial part. Record who approves the final notice and who verifies the required top-line statement.
This structure clarifies responsibility across HR, legal, operations, and technology teams. It also preserves a reviewable basis for the organization's determination and the language used in the notice.
The statute directs EDD to publish summaries of notices received under the new provision and a quarterly statewide summary of reported technology displacements. Those summaries make the reported subject matter part of public EDD reporting. The statute calls for summaries; organizations should not assume that every complete employer notice will be published in full.
Prepare notice content before January 1, 2027
A controlled preparation process helps identify relevant facts before a notice is drafted.
- Screen the event. Determine whether the planned action is a mass layoff, relocation, or termination under Cal-WARN. Verify the covered-establishment and event definitions against the statute.
- Assess the technology connection. Document whether AI or other automated technology is replacing or automating employment positions, and whether it caused the action in whole or substantial part.
- Collect the required details. Reconcile employee counts, classifications or occupations, work locations, and affected job functions with current workforce records.
- Identify the technology category. Assign a technical owner to describe the category or type of system in precise, supportable terms. Preserve the source material used to confirm the description.
- Update the notice template. Add the required statement at the top and create controlled fields for each additional disclosure. Route the draft for legal and operational review.
- Retain the evidence. Keep the assessment, source records, approvals, final notice, recipient list, delivery record, and any corrections together in a secure case file.
The sequence supports timely preparation and consistent review. It also helps distinguish facts established before notice issuance from explanations added later.
Notice delivery and evidence controls
SB 951 adds disclosure requirements but does not establish a new electronic delivery method. The underlying Cal-WARN framework requires written notice to specified recipients. Employers should verify permitted delivery procedures with counsel or the relevant authority rather than assume that electronic delivery alone satisfies every recipient's requirements.
A complete notice file should show what was approved, when it was issued, which recipients received it, and what evidence confirms delivery. Preserve the exact version sent and record any recipient-specific delivery method, acknowledgment, returned notice, or correction.
An evidence register can track each content obligation alongside its owner, source record, reviewer, and completion status. A separate notice log can capture dates, recipients, delivery methods, and exceptions. These records preserve accountability and support oversight reviews.

Actions for employers
Before the effective date, employers with California operations should review workforce-planning procedures, Cal-WARN templates, and cross-functional approval paths. Identify who evaluates technology-related causation and who supplies each required disclosure. Confirm that payroll, HR, operations, and technology records use consistent job classifications and work-location data.
When a covered event is under consideration, preserve the decision record and source information as the analysis develops. Do not wait until notice drafting to reconcile employee counts, job functions, or system descriptions. Establish a correction and escalation process for inconsistent or incomplete records.
Organizations should also monitor EDD guidance and statutory updates. SB 951 sets the disclosure requirements, while implementation questions can depend on the facts of a particular workforce action and applicable exceptions.
