Primary legal sources for California

In California, workers' compensation is generally the only remedy a hurt worker has against the employer, with narrow exceptions the Labor Code lists. A worker can still bring a claim against someone other than the employer, such as an equipment maker or a property owner. Most of those injury claims carry a two-year filing period.

Most people facing this question were hurt at work in a warehouse, a factory or a plant, or lost someone there, and are now dealing with medical bills, missed paychecks and the question of whether workers' compensation is the end of the road. If that is where you are, the hard part is usually not the injury itself but not knowing what California's rules allow, who else may be involved, and how much the clock matters. This page walks through those rules one at a time, as California's own statutes state them.

Why Workers' Comp Usually Isn't the Only Option in California

For a hurt worker, the first question is usually whether workers' compensation is all there is. Under Labor Code section 3602, where the conditions of compensation in Section 3600 are met, "the right to recover compensation is, except as specifically provided in this section and Sections 3706 and 4558, the sole and exclusive remedy of the employee or his or her dependents against the employer." If you were hurt on the job, that means a lawsuit against your own employer is generally closed off, except in the situations those sections describe.

That rule speaks only to the employer. Labor Code section 3852 provides that an employee's claim 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." Put simply, filing for workers' compensation does not by itself give up a claim against an outside company or person whose conduct contributed to the injury. When both tracks are open, the two can interact, and how money recovered from an outside party relates to benefits the employer or its insurer has paid is a question that commonly comes up in these dual-track cases.

A claim against an outside party usually rests on the general duty in Civil Code section 1714, subdivision (a): everyone is responsible for an injury caused to another by "want of ordinary care or skill in the management of his or her property or person," except so far as the injured person brought the injury on himself or herself. Ordinary care means the care a reasonable person would use in the same circumstances, and whether anyone fell short of it depends on the facts, not on the injury alone.

What is at stake is whether recovery is limited to workers' compensation benefits or may also include a civil claim. A conversation with an attorney can cover how these paths line up against what happened.

Warehouse, Factory, and Plant Accidents: Where These Rules Come Up

The accidents behind these cases tend to fall into familiar groups: a hand caught in a press or other machine; a fall from a mezzanine, a ladder or a loading dock edge; a forklift or pallet jack striking a worker, or a load shifting during loading and unloading; equipment that fails during use or starts up during servicing, the subject of the site's page on lockout/tagout failure injuries; and illness that develops after exposure to something in the air or on the skin at work. The site's page on warehouse accident claims looks more closely at the warehouse setting.

Power press injuries have their own California provision. Labor Code section 4558 concerns an action against an employer for the knowing removal of, or knowing failure to install, a point of operation guard on a power press, and it is one of the exceptions section 3602 names. For this section, "Employer" means "a named identifiable person who is, prior to the time of the employee's injury or death, an owner or supervisor having managerial authority to direct and control the acts of employees." That definition is narrow, so whether a press injury fits section 4558 turns closely on who did what before the injury.

Exposure cases run on a different clock, covered below under Code of Civil Procedure section 340.8.

The type of accident matters because it points toward which rules may apply: a guard removed from a press may raise section 4558, a defective machine may point to its maker, and an exposure illness may follow its own deadline. If you were hurt in one of these ways, the details that often shape the analysis are what machine or material was involved, who owned and maintained it, and who controlled the area where it happened.

Who May Be Responsible When a Worker Is Hurt

Responsibility after a workplace injury is often spread across more than one business, and California law treats each kind differently. For an injured worker, this is where the question of a civil lawsuit is decided: a claim beyond workers' compensation is generally possible only if an outside party, someone other than the employer, may be responsible.

The employer is the starting point, and under section 3602 workers' compensation is generally the exclusive remedy against it, subject to the exceptions that section lists, including section 4558.

Anyone else counts as "any person other than the employer" under section 3852. If you were hurt, the outside parties that may come up include:

  • The maker of the machine or equipment. A products liability claim is one that a product was defective and that the defect caused the injury. An accident alone does not show a defect; whether there was one, and whether it caused the harm, depends on the facts.
  • The owner of the building or site, if it is not the employer. A premises liability claim is one that a property owner or occupier failed to use ordinary care in keeping the property safe, which in California rests on the duty in section 1714(a).
  • A contractor, staffing company or other business that controlled part of the worksite, the equipment or the work itself, again measured against ordinary care.

Workers sometimes come across a property rule that does not fit the workplace. Civil Code section 846, subdivision (a), says an owner "owes no duty of care to keep the premises safe for entry or use by others for any recreational purpose," except as that section provides; subdivision (d) sets out the exceptions. That limit is tied to recreational entry, a different setting from coming onto property to work.

Sorting out who owned, maintained or controlled what is often the first thing an attorney looks at.

How California Handles Fault When More Than One Party Is Involved

Many injured workers worry that a moment of their own inattention ends any claim. In California it does not work that way. In Li v. Yellow Cab Co. (1975) 13 Cal.3d 804, the Supreme Court of California superseded the all-or-nothing rule of contributory negligence with a system of pure comparative negligence, which assigns liability in direct proportion to the amount of negligence of each of the parties.

Comparative fault means that responsibility for an accident is divided among everyone whose carelessness contributed to it, including the injured person. For a worker, your own share of fault, if there is one, is weighed alongside everyone else's rather than automatically closing the door.

A second rule governs how losses are divided among defendants. Under Civil Code section 1431.2, subdivision (a), in any action for personal injury, property damage or wrongful death based on comparative fault, "the liability of each defendant for non-economic damages shall be several only and shall not be joint," in direct proportion to that defendant's percentage of fault. Non-economic damages are losses like pain and suffering, as opposed to bills and lost wages. Each defendant answers for its own share of those losses, not the whole amount.

How fault might be divided depends on the facts and on what each party controlled, which is often where a claim with several parties becomes complicated.

Filing Deadlines That Apply to California Industrial Accident Claims

A statute of limitations is the law's deadline for filing a lawsuit; after it passes, a claim can be lost even if it was otherwise sound.

The general California rule is Code of Civil Procedure section 335.1: "Within two years: An action for assault, battery, or injury to, or for the death of, an individual caused by the wrongful act or neglect of another." That period applies to most injury and death claims against outside parties.

Exposure claims follow section 340.8, subdivision (a). For injury or illness based on exposure to a hazardous material or toxic substance, an action must be started no later than either two years from the date of injury, or two years after the plaintiff becomes aware, or reasonably should have become aware, of the injury, its physical cause, and enough facts to put a reasonable person on notice that the injury was caused or contributed to by someone's wrongful act. Subdivision (b) addresses actions for a death based on such exposure. This matters because illness from exposure can surface long after the work that caused it.

For a minor, Code of Civil Procedure section 352, subdivision (a), provides that the time a person entitled to sue was under the age of majority, or lacked the legal capacity to make decisions, is not part of the time limited for the action. Subdivision (b) says this does not apply to an action against a public entity or public employee on a cause of action for which a claim must be presented.

Claims against a government body have their own steps. Government Code section 945.4 bars a suit for money or damages until a written claim has been presented and acted upon, or deemed rejected, except as sections 946.4 and 946.6 provide. Government Code section 911.2, subdivision (a), requires a claim for death or injury to person to be presented "not later than six months after the accrual of the cause of action." Government Code section 945.6, subdivision (a), then sets when the lawsuit itself must be commenced, subject to its stated exceptions.

Which deadline governs depends on who may be responsible and when the claim accrued, and the dates involved are a natural subject for a conversation with an attorney.

What a California OSHA Citation Can Mean for an Injury Case

Families often hear that the state safety agency, Cal/OSHA, inspected the site or issued a citation, and wonder whether that settles who was at fault. Labor Code section 6304.5 reads: "It is the intent of the Legislature that the provisions of this division, and the occupational safety and health standards and orders promulgated under this code, are applicable to proceedings against employers for the exclusive purpose of maintaining and enforcing employee safety." The same section provides that neither the issuance of, nor the failure to issue, a citation shall "be admissible into, evidence in any personal injury or wrongful death action, except as between an employee and his or her own employer," and that Evidence Code sections 452 and 669 apply to the safety standards "in the same manner as any other statute, ordinance, or regulation."

For an injured worker, that means the safety standards and the enforcement process exist to keep workplaces safe. A citation is an agency's allegation that a standard was not met; it is not a court's finding that anyone is liable for an injury, and a citation at one site says nothing about any other business or industry.

Even so, an inspection creates records: what the inspector observed, what was cited, and whether the citation was contested or resolved. Those records describe the conditions at the time, which is why injured people and families often ask what inspection paperwork exists.

Records and Information That Often Matter in These Cases

The factual record is where duty, breach, causation and damages are either shown or not. If you were hurt, the records that usually matter include:

  • Medical records and treatment documentation, from the first visit onward.
  • Incident reports and any reports the employer prepared.
  • Maintenance, repair and inspection records for the machine or equipment.
  • Photos and video of the scene, the equipment and the injury.
  • Names and contact information of coworkers or others who saw what happened.
  • Cal/OSHA inspection records and any citations, with their status.
  • The product, equipment or vehicle involved, and purchase or order records if a product is at issue.

Families after a death often gather the same materials, along with records showing their relationship to the person who died.

When these records exist, they let the facts speak for themselves. When some are missing, a conversation with our attorney can cover what is available and what each piece may show. To talk through the records in a case like yours, you can request a case evaluation.

Wrongful Death Claims After a Fatal Industrial Accident in California

Losing a family member at work brings grief and, often, sudden financial strain at the same time. Wrongful death is a claim by certain family members for a death caused by someone else's wrongful act or neglect.

California names who may bring it. Under Code of Civil Procedure section 377.60, the claim may be asserted by the following persons or by the decedent's personal representative on their behalf, including under subdivision (a): "The decedent's surviving spouse, domestic partner, children, and issue of deceased children, or, if there is no surviving issue of the decedent, the persons, including the surviving spouse or domestic partner, who would be entitled to the property of the decedent by intestate succession." Who qualifies turns on the family relationship.

The two-year period in section 335.1 covers an action for the death of an individual caused by wrongful act or neglect; the exposure rule and public-entity steps may also apply.

After a death on the job, both systems may be in play. Workers' compensation remains the remedy against the employer, subject to section 3602's exceptions, while section 3852 preserves the right of action "for all damages proximately resulting from the injury or death against any person other than the employer." What any claim may lead to depends on the facts and is not assured.

Frequently asked questions

Can a worker injured in a California factory sue someone other than their employer?

Yes, Labor Code section 3852 preserves a claim against any person other than the employer. Workers' compensation is generally the exclusive remedy against the employer under section 3602, subject to its listed exceptions. Whether an outside party, such as a manufacturer or property owner, is responsible depends on the facts.

How long does an injured worker have to file a lawsuit in California?

Code of Civil Procedure section 335.1 sets two years for injury or death caused by another's wrongful act or neglect. Exposure claims follow section 340.8, which counts from the date of injury or from when the person became aware, or should have, of the injury, its cause and its link to a wrongful act. Public-entity claims add a six-month claim step.

What is workers' compensation and does it cover all industrial accident injuries in California?

Under Labor Code section 3602, where the conditions of compensation are met, workers' compensation is the employee's exclusive remedy against the employer, except as that section and sections 3706 and 4558 provide. It does not limit claims against others under section 3852. Whether a particular injury fits depends on the facts.

What does California's comparative fault rule mean for an injured worker?

Under Li v. Yellow Cab Co. (1975) 13 Cal.3d 804, California uses pure comparative negligence, assigning liability in direct proportion to each party's negligence. A worker's own share is weighed rather than automatically barring the claim. Civil Code section 1431.2(a) makes each defendant's liability for non-economic damages several only.

Who may bring a wrongful death claim after a fatal industrial accident in California?

Code of Civil Procedure section 377.60(a) names the surviving spouse, domestic partner, children and issue of deceased children, or, if there is no surviving issue, those entitled to the decedent's property by intestate succession. A personal representative may assert it on their behalf. Section 335.1's two-year period applies to death claims.

Does a Cal/OSHA citation mean the employer is automatically liable for an injury?

No. A citation is an agency's allegation, not a court's finding of liability. Under Labor Code section 6304.5, a citation, or the failure to issue one, is not admissible in a personal injury or wrongful death action "except as between an employee and his or her own employer," and Evidence Code sections 452 and 669 apply to the safety standards "in the same manner as any other statute, ordinance, or regulation." Inspection records can still describe workplace conditions.

What is the deadline for filing a claim against a California government employer or public entity?

Government Code section 911.2(a) requires a claim for death or injury to person within six months after the cause of action accrues. Section 945.4 bars suit until the claim is acted upon or deemed rejected, and section 945.6(a) sets when suit must then be commenced. Minority tolling does not apply here under Code of Civil Procedure section 352(b).

Can a child's industrial accident claim be filed after the standard two-year period in California?

Code of Civil Procedure section 352(a) provides that time spent under the age of majority is not part of the time limited for the action. Section 352(b) says this does not apply to an action against a public entity or public employee on a cause of action for which a claim must be presented.
