Workers' compensation is the oldest social insurance program; it was adopted in most states, including California, during the second decade of the 20th century. It is a no-fault system, meaning that injured employees need not prove the injury was someone else's fault in order to receive workers' compensation benefits for an on-the-job injury.

The workers' compensation system is premised on a trade-off between employees and employers. Employees are supposed receive the prompt delivery of defined statutory workers' compensation benefits for on-the-job injuries, and in return, the defined workers' compensation benefits are, for the most part, the exclusive remedy for injured employees against their employer, even when the employer negligently caused the injury.

The Workers’ Compensation Claim Management Unit (WCCMU) operates and monitors a complete permissibly self-insured workers’ compensation program ensuring the full provision of benefits under the law to employees whose injuries arose in the course and scope of employment. This program oversees the administration of approximately 25,000 workers’ compensation claims and is the largest of any local governmental agency in California. Currently, the County of Los Angeles contracts with private firms charged with the administration of workers’ compensation claims. These firms are called workers’ compensation third party administrators. The WCCMU provides continuous on-site workers’ compensation third party administration contract monitoring. Additionally, the WCCMU provides customer service designed to assist injured workers and departments resolve workers’ compensation claim issues by providing subject matter expertise.
