(a) The claim of an employee, including, but not limited to, any peace officer or firefighter, for compensation does not affect their claim or right of action for all damages proximately resulting from the injury or death against any person other than the employer.
What does California Labor Code §3852 actually preserve?
Section 3852 establishes the California rule that an injured worker hurt by a non-employer third party keeps the right to sue that third party for full damages.
Section 3852 is California's rule that an injured worker hurt at work by someone other than the employer keeps the right to sue that third party for full money damages, including pain and suffering, lost future earnings, and loss of consortium. The civil suit runs alongside the comp claim. Certified Specialist Eman Yazdchi (California Board of Legal Specialization, State Bar of California) coordinates both files.
California Labor Code §3852 preserves the California injured worker's right to sue a third-party tortfeasor for the same industrial injury covered by the workers' compensation claim. The §3852 California rule means the California Labor Code §3601, California's exclusive-remedy bar that prevents the worker from suing the employer for the same industrial injury, exclusive-remedy bar against the employer does NOT extend to third parties whose negligence or defective product contributed to the injury. The comp claim flows against the employer or insurer; the §3852 civil action flows against the third party. Both proceed at the same time on different tracks.
Who is a §3852 California "third party" for an injured worker?
A third party is anyone other than the worker's own employer, a negligent driver, a defective-product manufacturer, a property owner, or a contractor on a multi-employer job site.
Under California Labor Code §3852, a California third party is any non-employer whose conduct contributed to the industrial injury. Common third parties include: a negligent driver who collided with a worker on a delivery route, a defective product manufacturer (forklift, power tool, ladder), a property owner where the worker was injured on premises, a general contractor when the worker was a subcontractor's employee, or another company's employee whose negligence caused the injury. The §3852 California rule unlocks tort recovery against each.
What damages can a California §3852 third-party action recover?
Third-party damages include medical expenses, lost earnings, pain and suffering, future earnings, and loss of consortium, none of which workers' compensation alone covers.
Under California Labor Code §3852, the California third-party civil action recovers ordinary tort damages, economic damages (medical bills, lost wages, future earnings loss) AND non-economic damages (pain and suffering, emotional distress, loss of consortium). The §3852 recovery captures categories of damage NOT available in the comp system, which does not pay pain and suffering. The §3852 California civil action runs on tort principles, separate from the no-fault California Labor Code §3600 framework.
How does §3852 interact with §3856 allocation of the third-party recovery?
Section 3856 governs how the civil recovery is allocated between the worker and the carrier holding a lien for benefits already paid in the comp case.
Under California Labor Code §3852 (right to sue) and California Labor Code §3856 (allocation), once a California third-party recovery is obtained, §3856 allocates it in fixed priority: litigation costs and attorney fees first, then the employer/insurer's subrogation lien for comp benefits paid (California Labor Code §4600 medical, California Labor Code §4653 TD, California Labor Code §4660 PD), with the remainder to the worker. The §3852 right plus §3856 allocation is the complete California third-party framework.
How does §3852 interact with §3601 exclusive remedy against the employer?
Section 3601, the exclusive remedy rule, bars suing the employer in tort but does not bar the separate suit against the third-party tortfeasor under section 3852.
Under California Labor Code §3601 and California Labor Code §3852, California workers' compensation is the exclusive remedy against the employer, but California Labor Code §3852 carves out third-party civil actions. A California worker injured in a vehicle collision on a delivery route receives California Labor Code §3601 comp benefits AND can sue the at-fault driver under §3852. The §3852 recovery is in addition to comp, not in lieu, subject only to the California Labor Code §3856 subrogation lien allocation.
WCIRB's 2024 medical loss data shows California carriers paid out approximately $4.2 billion in medical benefits, with about 18% of medical disputes routed through IMR under California Labor Code §4610.5, the leading cause of treatment-delay grievances in the closed-claim survey.

What does California Labor Code §3852 actually preserve for the injured worker?
California Labor Code §3852 preserves the California injured worker's right to sue a third-party tortfeasor for the same industrial injury covered by the workers' compensation claim. The §3852 California rule confirms the California Labor Code §3601 exclusive-remedy bar against the employer does NOT extend to third parties whose negligence or defective product contributed to the injury. The comp claim flows against the employer or insurer; the §3852 California civil action flows against the third party. Both proceed at the same time on different tracks.
Who is a §3852 California "third party" in a workers' comp case?
Under California Labor Code §3852, a California third party is any non-employer whose conduct contributed to the industrial injury. Common California §3852 third parties include: a negligent driver who collided with a worker on a delivery route, a defective product manufacturer (forklift, power tool, ladder, scaffolding), a property owner where the worker was injured on premises, a general contractor when the worker was the employee of a subcontractor, or another company's employee whose negligence caused the injury. The §3852 rule unlocks tort recovery against each.
What damages can a California §3852 third-party action actually recover?
Under California Labor Code §3852, the California third-party civil action recovers ordinary tort damages, economic damages (medical bills, lost wages, future earnings loss) AND non-economic damages (pain and suffering, emotional distress, loss of consortium). The §3852 California tort recovery captures categories of damages NOT available in the workers' comp system, which does not pay pain and suffering. The §3852 civil action runs on full tort principles, with causation and fault analysis, separate from the no-fault California Labor Code §3600 comp framework against the employer.
How does California §3852 actually interact with §3856 third-party allocation?
Under California Labor Code §3852 (right to sue) and California Labor Code §3856 (allocation), once a California third-party recovery is obtained, §3856 allocates it in fixed priority: litigation costs and reasonable attorney fees first, then the employer/insurer's subrogation lien for comp benefits already paid (California Labor Code §4600 medical, California Labor Code §4653 TD, California Labor Code §4660 PD), with the remainder to the injured worker. The §3852 right plus §3856 California allocation is the complete third-party recovery framework, right to sue, then ordered distribution.
How does §3852 interact with the §3601 exclusive-remedy rule against the employer?
Under California Labor Code §3601 and California Labor Code §3852, California workers' compensation is the exclusive remedy against the employer, but California Labor Code §3852 carves out third-party civil actions entirely. A California worker injured in a vehicle collision while on a delivery route receives California Labor Code §3601 comp benefits from the employer or insurer AND can sue the at-fault driver under §3852 in civil court. The §3852 California recovery is in addition to comp, not in lieu of it, subject only to the §3856 subrogation lien allocation when the worker recovers.
