California protects employees who serve as volunteer emergency responders and are called into action during natural disasters.

California law makes it unlawful for an employer to fire or otherwise discriminate against employees who take a temporary leave of absence to respond to an emergency in their roles as volunteer firefighters, emergency rescue personnel, or reserve peace officers.

Generally, the law does not require advance notice, except for certain health care workers. Employees who are health care providers must inform their employers both when they become designated as emergency rescue personnel and when they are notified of their duty in an emergency.
