In California, all employers with one or more employees are required to carry workers’ compensation insurance. This can be obtained through a private insurer or by qualifying for self-insurance if the business meets specific criteria. Unlike some states, California mandates that all corporate officers and directors be covered unless they own the entire business. Additionally, the state provides extensive support for injured workers, including medical treatment, temporary disability benefits, and vocational rehabilitation. Compliance is strictly enforced by the California Division of Workers’ Compensation, with severe penalties for non-compliance to ensure workers are protected.
