Employers must provide written notice to employees at least 90 days before deploying any AI tool used for employment decisions or workplace surveillance, with existing tools requiring notice by February 1, 2027

Required notice must include the AI tool's purpose, what employment decisions it affects, what worker data is collected and how it's stored, whether jobs will be automated, and results of any risk assessments

Employers must maintain and annually distribute an updated list of all workplace AI tools in use, and workers must sign to confirm they received and understand the notice before the tool can be used

Violations are enforceable by the Labor Commissioner, public prosecutors, or through private civil action, with penalties of up to $500 per employee per violation plus potential punitive damages and attorney's fees

The law applies to all California employers including state and local governments, charter cities, universities, and school districts, covering both employees and independent contractors
