Workers' Compensation Glossary of Terms

WORKERS’ COMPENSATION GLOSSARY OF TERMS

Workers' compensation is the oldest social insurance program. While this glossary was created for the state of California, many of these terms are applicable in all states. Use this glossary of terms to better understand workers' compensation.

California only: California has a no-fault system, which means 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.
