What happened
California Governor Gavin Newsom signed Senate Bill 951, amending the Cal/WARN Act to require specific disclosures for mass layoffs, relocations, or terminations caused in whole or in substantial part by artificial intelligence or other automated technology. The law takes effect on January 1, 2027.
Governor Gavin Newsom signed Senate Bill 951, which updates California’s workforce disclosure laws by adding new requirements to the Cal/WARN Act. The bill specifically targets employment displacement caused by artificial intelligence or other automated systems. The mandate takes effect on January 1, 2027.
Under SB 951, if a mass layoff, relocation, or termination is caused in whole or in substantial part by AI or automated technology, the employer’s notice must include specific details. These include the number, , and work location of affected employees, the specific job functions being automated, and the category or type of AI technology used. The notice must also prominently state, “This notice is for a technology displacement.”
The bill amends Labor Code sections 1400.5, 1401, and 1402.7. It requires the California Employment Development Department (EDD) to publish a summary of these “technological” displacements as part of its regular Cal/WARN data reporting on its website. Additionally, the EDD is tasked with submitting a report to the Legislature by January 1, 2028, analyzing AI’s effects on business hiring practices.
The existing scope of Cal/WARN remains unchanged, applying to industrial or commercial facilities with 75 or more current employees or those employed within the previous 12 months. The new AI-specific disclosures are additive to existing requirements such as rapid response coordination content and contact information.

Why it matters
This legislation creates a new transparency standard for AI-driven workforce reductions in the United States. By mandating that employers specify the type of AI technology used and the job functions being automated, the law provides data for researchers and policymakers to track the practical impact of automation on employment. It distinguishes AI-caused displacements from other economic factors, offering a clearer picture of how AI is reshaping the labor market in California, the largest state economy.
This law marks a significant shift in how AI-driven labor changes are regulated in the U.S. By requiring explicit disclosure of the AI technology used, it moves beyond generic layoff notices to provide granular data on automation trends.
The requirement for the EDD to publish summaries of technological displacements creates a public that can be used to monitor the scale and nature of AI’s impact on specific industries and job roles in California.
For employers, this introduces a new compliance burden, requiring them to identify and document the specific AI systems responsible for workforce reductions. This may influence how companies structure and document their automation strategies.
The upcoming legislative report due in 2028 will provide further insight into the broader economic and social effects of AI on hiring practices, potentially informing future policy decisions.

What to watch next
Employers will need to update their Cal/WARN notice templates to include the new mandatory statements and data points regarding AI usage. The California Employment Development Department (EDD) will begin publishing summaries of these technological displacements, and a legislative report on AI's effects on hiring practices is due by January 1, 2028.
Companies operating in California with 75 or more employees should review their layoff and termination procedures to ensure compliance with the new disclosure requirements effective January 1, 2027.
Researchers and labor advocates will likely analyze the EDD’s published data to assess the real-world impact of AI on employment in key sectors.
The 2028 legislative report may lead to further regulatory actions or adjustments based on the observed effects of AI on hiring and workforce composition.
