Every employer except the state shall secure the payment of compensation in one or more of the following ways: (a) By being insured against liability to pay compensation by one or more insurers duly authorized to write compensation insurance in this state. (b) By securing from the Director of Industrial Relations a certificate of consent to self-insure either as an individual employer, or as one employer in a group of employers, which may be issued upon furnishing proof satisfactory to the director of ability to self-insure and to pay any compensation that may become due to his or her employees.
What does Labor Code 3700 require?
Labor Code 3700 requires every California employer to secure workers' comp insurance through an admitted carrier or qualify as a certified self-insured employer. Both routes are mandatory. No employer is exempt except the state.
Labor Code 3700 is the insurance mandate. Without coverage, the no-fault bargain under Labor Code 3600 cannot function. An uninsured employer faces criminal and civil consequences. The injured worker still gets paid.
Eman Yazdchi is a Certified Specialist in workers' compensation law, certified by the California Board of Legal Specialization, State Bar of California. He enforces Labor Code 3700 coverage obligations on every file where the employer's insurance status is in question.
Which California employers must comply with Labor Code 3700?
Every California employer with at least one employee must comply, regardless of whether the worker is full-time, part-time, or temporary. The mandate reaches every industry and every type of employer.
Labor Code 3700 covers construction, agriculture, retail, restaurant, manufacturing, healthcare, and professional services. Worker classification under Labor Code 2775 determines who counts as an employee. Once classified as employees, Labor Code 3351 confirms coverage regardless of immigration status. The employer must insure the full workforce.
What are the two Labor Code 3700 compliance routes?
Route one is purchasing a policy from an insurer admitted to transact comp business in California. Route two is qualifying as a self-insured employer through the Department of Industrial Relations Office of Self-Insurance Plans.
The self-insurance route requires posting security and demonstrating financial strength. The employer must report ongoing financial information to the DIR. Self-insurance is available to larger employers with sufficient assets. The Labor Code 3700 requirement is non-delegable. A contractor cannot shift it to a subcontractor or staffing agency.
What consequences follow a Labor Code 3700 violation?
Three layers of consequence apply at once: a stop-work order, a Labor Code 3700.5 misdemeanor with civil penalties of $10,000 per employee, and a Labor Code 3706 civil suit by the injured worker outside the usual exclusive-remedy bar.
The DIR issues a stop-work order under Labor Code 3710.1. The employer faces a Labor Code 3700.5 misdemeanor and civil penalties of $10,000 per employee. Under Labor Code 3706, the injured worker may file a civil suit. That suit falls outside the Labor Code 3601 exclusive-remedy bar.
How does Labor Code 3700 interact with the Uninsured Employers Benefits Trust Fund?
When the employer is uninsured, the Uninsured Employers Benefits Trust Fund steps in to pay the worker's comp benefits. The UEBTF then pursues reimbursement directly from the uninsured employer.
The UEBTF pays medical care under Labor Code 4600. Temporary disability flows under Labor Code 4653. Permanent disability is paid under Labor Code 4660. The injured worker is not left without benefits. The UEBTF recovers from the employer afterward.
