California Will Soon Force Employers to Name AI as a Layoff Cause

Starting January 1, 2027, any California employer covered by the state's WARN Act will have to state in writing, at the top of the layoff notice itself, that "This notice is for a technology displacement" — whenever AI or other automation caused the job cuts "in whole or in substantial part." Governor Newsom signed SB 951 into law late yesterday, and it applies to every establishment with 75 or more employees that lays off 50 or more people within a 30-day period.

That is the existing WARN framework, and the 60-day written notice clock to affected employees, the Employment Development Department (EDD), the local workforce development board, and the chief elected official of each affected city and county stays exactly as it was. What changes is the content of the notice.

Four new disclosure elements

Under SB 951, a mass layoff, relocation, or termination driven by an AI system or other automated technology replacing positions must include four additions:

• The statement "This notice is for a technology displacement," placed at the top of the notice;
• The number of layoffs substantially caused by automation, along with the classification or occupation and work location of the affected jobs;
• The job functions performed by the replaced workers that will be automated;
• The specific category or type of AI system or automating technology that substantially caused the displacement.

The law also inserts a definition of "artificial intelligence" into the WARN Act: any engineered or machine-based system that varies in its level of autonomy and can infer from its inputs how to generate outputs influencing physical or virtual environments. That definition is broad enough to capture a great deal of ordinary workforce software that employers might not immediately think of as AI.

What this means for your market position

The more consequential change for workers and job seekers is publication. The EDD will post a summary of these notices on its website as part of its regular WARN Act data reporting, plus a quarterly statewide summary of technology displacements. California already publishes WARN notices, but a searchable, state-maintained tally of which employers are automating which jobs will give job seekers, unions, and plaintiffs' attorneys direct visibility into where specific occupations are being absorbed by machines. If you work in a role that appears repeatedly in those quarterly summaries, that is concrete, employer-level evidence about the durability of your occupation — not anecdote.

For employers, the exposure is reputational as much as legal. What gets filed becomes public and quotable, and the description of the technology and the automated job functions must be consistent with what the company says elsewhere.

Five preparation steps before 2027

Employers have roughly two years. Legal practitioners advising them suggest five moves:

1. Decide how to characterize causation and document it contemporaneously — capture the business case for any workforce reduction, including non-technology drivers, rather than reconstructing it after a notice is challenged.
2. Rebuild the WARN notice template now, adding the four new elements and placing the technology displacement statement at the top where the statute requires it.
3. Map AI tools to the roles they touch. An employer cannot describe the system that caused a displacement if nobody has inventoried what is deployed and what work it absorbs — work that overlaps with inventory obligations under other California AI laws.
4. Loop in legal, communications, and investor relations before the notice goes out.
5. Watch the EDD study. The law directs the EDD to report to the Legislature by January 1, 2028, on how AI is affecting hiring across industries and occupations.

That report matters beyond compliance. It may recommend a new notice requirement for employers that permanently stop hiring for a position because of automation — even when nobody is laid off, meaning hiring freezes caused by AI could eventually become disclosable events. This is the second time in under two years that California has ordered a study of AI-driven job loss, following the Governor's executive order directing state agencies to examine the same question.
