In California, Labor Code §3700.5 makes an employer's failure to carry workers' compensation insurance a misdemeanor — punishable by county jail and fines, plus civil penalties of $10,000 per employee on the date of the violation when an injury has occurred (or $2,000 per employee with a higher aggregate cap when no injury has occurred).
California Labor Code §3700.5 makes a California employer's failure to carry workers' compensation insurance — the California Labor Code §3700 violation — a misdemeanor offense. Under §3700.5, the California employer who fails to secure the payment of workers' compensation benefits as §3700 requires is criminally exposed to county-jail time and fines, plus separate civil penalties calculated on a per-employee basis. The §3700.5 California rule is the criminal counterpart to the California Labor Code §3700 insurance mandate; the legislature backed up the comp coverage requirement with criminal liability to deter California employers from operating uninsured.
Under California Labor Code §3700.5, a California employer who violates California Labor Code §3700 is guilty of a misdemeanor punishable by imprisonment in county jail and by a fine. The §3700.5 California criminal exposure attaches to the responsible corporate officers and operators — not just the corporate entity. The California district attorney has prosecutorial authority over §3700.5 cases, and the Department of Industrial Relations refers California uninsured-employer cases for prosecution. The §3700.5 California criminal framework runs in parallel with the §3700.5 California civil-penalty framework — both apply to the same uninsured California employer at once.
Under California Labor Code §3700.5, the California civil penalty is calculated per employee on the date of the violation. When an injury has occurred during the uninsured period, the §3700.5 California civil penalty is $10,000 per employee on the date of the violation. When no injury has occurred but the California employer was nonetheless uninsured, the §3700.5 California civil penalty is $2,000 per employee on the date of the violation, subject to an aggregate cap. The §3700.5 California per-employee calculation is what makes the civil exposure escalate sharply for California employers with sizable workforces.
Under California Labor Code §3700.5 (criminal + civil penalties) and California Labor Code §3706 (civil tort liability to the worker), the California uninsured employer faces three simultaneous layers of consequence. The §3700.5 California layer is the misdemeanor + per-employee civil penalty enforced by the state. The California Labor Code §3706 California layer is the injured worker's right to sue the uninsured employer in civil court outside the California Labor Code §3601 exclusive-remedy bar — with a statutory presumption of employer negligence. The Uninsured Employers Benefits Trust Fund pays the worker's comp benefits and seeks reimbursement from the uninsured California employer as the fourth layer.
Under California Labor Code §3700.5, California enforcement typically begins with a stop-work order from the Department of Industrial Relations when a worksite inspection or injury claim reveals the California employer was uninsured. The §3700.5 California civil penalties are then assessed administratively, with a hearing right. The §3700.5 California criminal referral goes to the district attorney's office for the county where the violation occurred. Many California §3700.5 cases resolve through stipulated penalty assessments and resumption of coverage; serious or repeat California offenders face active criminal prosecution and substantial civil exposure.
