California Bans Employers From Using AI to Fire Workers or Track Emotional States

California has enacted laws prohibiting employers from using artificial intelligence to make firing decisions or track workers' emotional states, placing the state at the forefront of AI workplace regulation in the United States.

The legislation bars companies from relying on AI systems as the sole or primary basis for terminating an employee's job. Employers must ensure that a human decision-maker reviews and approves any AI-generated recommendation before a worker is dismissed.

A separate provision bans the use of AI tools that monitor or infer employees' emotional states, including systems that analyze facial expressions, voice tone, or physiological signals to assess mood or stress levels. Such tools have been marketed to employers as a way to measure worker engagement or detect burnout, but critics say they are invasive and unreliable.

The laws apply to companies operating in California, which is home to many of the world's largest technology companies and employs millions of workers across industries including retail, logistics, and healthcare.

Supporters of the legislation, including labor unions and worker advocacy groups, say the laws are necessary to protect employees from opaque algorithmic decisions that can be difficult to challenge or appeal. They argue that AI systems trained on historical data can perpetuate bias and that workers deserve to know when AI is being used to evaluate their performance.

Business groups and some technology companies have pushed back, arguing that the restrictions could slow the adoption of AI tools that improve workplace safety, reduce errors, and help managers identify workers who need support.

California's AI workplace laws are part of a broader wave of state-level regulation as federal lawmakers have struggled to pass comprehensive AI legislation. Similar bills are under consideration in New York, Illinois, and Washington.
