Employment: technological displacement: notice.
Summary
Existing law, the California Worker Adjustment and Retraining Act (Cal/WARN Act) , prohibits an employer from ordering a mass layoff, relocation, or termination at a covered establishment unless, 60 days before the order takes effect, the employer gives written notice of the order to the employees affected by the order and to the Employment Development Department and certain local officials. Existing law makes an employer who fails to give specified notice regarding a mass layoff, relocation, or termination subject to a civil penalty of not more than $500 for each day of the employer's violation. This bill would revise the Cal/WARN Act to also require an employer giving notice of a mass layoff, relocation, or termination caused in whole or in substantial part by an artificial intelligence (AI) system or other automated technology replacing or automating employment positions to include certain information in the notice, including the job functions performed by workers that will be automated by AI or other automated technology. The bill would require the department to publish a summary of the notices received on its internet website and to post a quarterly statewide summary of technological displacements reported. The bill would require the department, on or before January 1, 2028, to submit a report to the Legislature on artificial intelligence's effects on business hiring practices, including its impact on industries and occupations at the state and regional level. The bill would repeal the provision requiring that report on January 1, 2029.
