Your case is our cause. Workers' Compensation Division P.O. Box 276130.Sacramento, CA 95827 (916) 876-5251 e-mail us. This guidebook gives an overview of the California workers' compensation system. ERISA's notion of a "health plan" (a distinct legal entity created when an employer promises to provide and pay for employee health benefits) is often confusing. All California employers must provide workers' compensation benefits to their employees under California Labor Code Section 3700. There are no cases that in the recent past have supported the assertion that ERISA preempts state workers' compensation laws. Failure to provide the form can lead to financial penalties for the County. ERISA section 510 makes it unlawful for any person to discharge, fine, suspend, expel, discipline, or discriminate against a participant or beneficiary. Medicallegal reports are prepared in the context of workers' compensation law, which has its own logic and definitions.
