If you were assaulted, threatened, or injured during a violent incident at your California workplace, you are probably asking two questions: does workers' comp cover this, and is there anything else you can do? The answers depend on who attacked you, what kind of injuries you suffered, and how quickly you act.
We have recovered over $150,000,000 for injured workers in Southern California. Workplace violence claims are among the most mishandled cases in the system, employers and insurers often push back hard, and injured workers leave money on the table by not understanding all the claims available to them. Here is what you need to know.
Quick summary:
- Physical injuries from workplace violence are almost always covered by California workers' comp.
- Psychiatric injuries like PTSD qualify when work was at least 51% responsible.
- Coworker assaults are generally covered unless the conflict was purely personal.
- Customer or stranger attacks on the job are covered because your job put you in that position.
- You may also have a separate personal injury claim if the attacker was a third party.
- Employer security failures can matter for related civil claims, but not against the employer directly.
- Insurers routinely argue these claims are not work-related. Expect a fight.
- You have 30 days to report the injury to your employer. That deadline is real.
1. Workplace Violence Injuries Are Often Compensable Under Workers' Comp
In California, a workplace violence injury is covered by workers' comp if it arose out of and in the course of employment under California Labor Code Section 3600, the attacker does not have to be a coworker.
Cal. Lab. Code §3600 sets the basic rule: your injury must arise out of and occur in the course of your employment. For workplace violence, California courts have interpreted this broadly. You do not need to prove that your job caused the violence, only that your employment placed you in the situation where the violence occurred. A cashier robbed at gunpoint, a nurse attacked by a patient, a security guard assaulted on patrol: all three are in covered territory because their jobs put them there.
The DWC handles the intake and processing of these claims, and the WCAB adjudicates disputed cases. If your employer's insurer denies your claim, the WCAB is where it gets resolved.
Practical takeaway: Being at work, or performing work duties, when the attack happens is the foundation of your claim. Document that clearly from day one.
2. The Types of Incidents That Typically Qualify
Qualifying incidents cover a wide range, including physical assaults by another person, armed robberies, sexual assaults, and active-shooter events that occur on the job or while performing work duties. If the violent event happened on employer premises during your shift, or while you were doing something your job required, it almost certainly meets the arising-out-of-employment test.
California law does not require the attacker to intend to harm you specifically, or to know you at all. A stray blow during a robbery qualifies. Being knocked down while trying to help a coworker escape a violent situation qualifies. California's workers' compensation system is a no-fault system: you do not need to prove your employer was negligent to receive benefits.
Industries with the highest exposure include healthcare and social services, retail, hospitality, public transit, corrections, and private security. Workers in those industries should understand their risk is elevated and their claims are well-established under California law.
Practical takeaway: You do not need to prove your employer did anything wrong. You need to prove the injury happened at work. Those are two very different burdens.
3. How Coworker-on-Coworker Assaults Are Usually Handled
A coworker assault is generally covered by workers' comp as long as the fight had some connection to the workplace, the moment it becomes purely personal, the claim gets more complicated.
When a coworker attacks you, the workers' comp insurer will almost always investigate whether the conflict was work-related or purely personal. California courts apply a "work-connection test." If the dispute arose from a work schedule disagreement, a task assignment, a workplace rivalry, or a conflict that started at work, even if it escalated off the clock, it is more likely to be covered. If two coworkers had a long-running personal feud that had nothing to do with work and one attacked the other during a shift, the insurer will argue the injury was personal in nature and therefore not compensable.
This is one of the most litigated issues in workplace violence workers' comp cases. Witness statements from other employees, HR complaint records, prior incident reports, and manager observations all become critical evidence. Do not assume because the fight happened at work that coverage is automatic, and do not assume it is denied because a coworker was involved.
Under Cal. Lab. Code §3601, workers' comp is generally the exclusive remedy against your employer when a coworker injures you. A separate civil lawsuit against the coworker personally is possible in some circumstances, but the exclusive remedy bar applies to the employer itself.
Practical takeaway: Preserve every piece of evidence that connects the conflict to work duties. That evidence is the difference between a covered claim and a denied one.
4. What Happens When the Attacker Is a Customer or Stranger
When the person who attacked you is a customer, client, patient, or a stranger who entered your employer's premises, your workers' comp claim is on solid ground. Your employment is what exposed you to that person and that risk. California courts have consistently held that third-party attacks on job sites are compensable when the work relationship is what placed the employee in harm's way.
This principle covers a wide range of workers: a pharmacy technician attacked by a shoplifter, a hospital nurse assaulted by a patient's family member, a delivery driver robbed during a delivery, a convenience store clerk threatened at gunpoint. In each case, the job created the exposure to the risk.
Workers' comp will cover your medical treatment, temporary disability (TD) payments, which replace a portion of your lost wages, and permanent disability (PD) benefits if your injuries have lasting effects. Under Cal. Lab. Code §4600, your employer's insurer is required to provide all medical treatment reasonably required to cure or relieve your injury.
Practical takeaway: Customer and stranger attacks are among the strongest workplace violence workers' comp claims. If the insurer denies this type of claim, challenge it.
5. Why Psychological Injuries From Violence Can Also Qualify
Psychiatric injuries like PTSD are compensable under California workers' comp when work was at least 51 percent responsible for the condition, as required by California Labor Code Section 3208.3.
A workplace assault does not only leave physical injuries. PTSD (post-traumatic stress disorder), acute stress disorder, major depressive disorder, and severe anxiety are all documented consequences of workplace violence. California workers' comp covers these psychiatric injuries under Cal. Lab. Code §3208.3, which requires that work was at least 51% responsible for the psychiatric condition.
An assault, robbery, or active-shooter situation at work can easily satisfy that threshold. The psychiatric injury claim is evaluated by a QME (qualified medical evaluator), a physician approved by the DWC, who reviews your medical records, employment history, and any pre-existing conditions. Insurers often argue that a pre-existing mental health condition breaks the causal chain; your medical evidence and the QME's opinion are the tools that rebut that argument.
If you are still employed at the time of the psychiatric claim, a separate rule applies: you must have worked for the employer for at least six months for a purely stress-based psychiatric claim. However, a claim rooted in a specific traumatic event, like a violent assault, is generally exempt from that six-month requirement under Cal. Lab. Code §3208.3.
Practical takeaway: Get a psychiatric evaluation and formal diagnosis as soon as possible after a workplace violence incident. Delay between the event and treatment is a gap insurers use to argue the condition is not work-related.
6. When a Third-Party Claim May Exist Alongside Workers' Comp
If the person who attacked you was not your employer or a coworker, you may have a personal injury lawsuit against that third party in addition to your workers' comp claim.
Workers' comp is the exclusive remedy against your employer. It is not the exclusive remedy against everyone. If a third party, a customer, a contractor on the job site, a property owner, a vendor's employee, or any non-coworker, caused your injuries, California law allows you to pursue a personal injury lawsuit against that party at the same time your workers' comp claim is open.
This is significant because personal injury damages go far beyond what workers' comp pays. Workers' comp does not pay for pain and suffering. A personal injury lawsuit can. Workers' comp replaces only a portion of your lost wages. A civil judgment can recover full economic losses. The combination of both claims, handled correctly, is where injured workers recover the most.
Under Cal. Lab. Code §3852, if you win or settle a third-party lawsuit, your employer's workers' comp insurer has a lien against that recovery for the benefits it already paid you. That lien is negotiable, and an experienced attorney manages it so you keep as much of the civil recovery as possible.
If you have a potential third-party claim, visit our personal injury practice area to understand how both claims work together.
Practical takeaway: If the attacker was not your employer or a coworker, do not settle your workers' comp claim before exploring the third-party civil claim. The two paths together are worth far more than either one alone.
7. How Employer Security Failures Can Matter for Related Claims
Employer security failures, ignored threats, broken cameras, inadequate staffing, do not give you a civil claim against your employer, but they may support a claim against a third-party property owner.
California's workers' comp system is the exclusive remedy against your employer for physical injuries sustained at work, even if your employer was negligent. You cannot sue your employer in civil court for failing to install adequate lighting or ignoring credible threats against employees. Workers' comp replaces that civil claim.
However, if your employer leases space from a third-party property owner, or if a security contractor provided inadequate services, those third parties are not shielded by your employer's workers' comp exclusivity. A property owner who knew about prior violent incidents on the premises and failed to address them may carry civil liability for a subsequent assault on a tenant's employee. A security company that provided untrained guards or was demonstrably understaffed may face a negligence claim.
Documenting security failures matters for another reason: it strengthens the factual record that the working environment created the risk, supporting the "arising out of employment" element of your workers' comp claim. Photographs of broken cameras, HR records showing prior threats were reported and ignored, incident logs, and staffing schedules are all evidence worth preserving.
Practical takeaway: Keep your employer's security failures in the record even if you cannot sue your employer directly. That documentation supports both your workers' comp claim and any third-party civil claim.
8. Common Employer Defenses in These Cases
Employers and their workers' comp insurers fight these claims more aggressively than many injured workers expect. Understanding the defenses in advance helps you prepare.
The most common defenses are:
- "The injury was personal, not work-related." This argument is most common in coworker assault cases. The insurer claims the conflict had no connection to your job duties or the work environment. Counter it with HR records, witness statements, and any documentation of how the dispute started.
- "You were the aggressor." Under Cal. Lab. Code §3600, a worker who initiates a physical altercation may be found to have forfeited coverage for injuries arising from that conduct. Witness accounts of who started the confrontation are critical.
- "The psychiatric claim does not meet the 51% threshold." Insurers send claimants to their own medical examiners who may attribute the psychiatric condition to pre-existing factors. Your attorney should request a QME panel through the DWC and ensure your treating physician documents the causal connection to the workplace event specifically.
- "You failed to report on time." Delayed reporting gives insurers an opening to argue they were prejudiced in their investigation. Report immediately, always.
Each of these defenses is beatable with the right documentation and medical evidence. The workers' comp practice area page explains how our attorneys handle disputed claims from initial denial through the WCAB hearing process.
Practical takeaway: An insurer denying a workplace violence claim is not the end of the road. It is the beginning of a dispute process where the facts, not the insurer's first judgment, determine the outcome.
9. Steps to Protect Your Claim After a Workplace Violence Incident
You have 30 days under California Labor Code Section 5400 to report a workplace injury to your employer, missing that window can jeopardize your entire claim.
Taking the right steps immediately after a workplace violence incident protects your health and your legal rights simultaneously.
1. Report the incident to your employer in writing. Under Cal. Lab. Code §5400, you have 30 days to notify your employer of a workplace injury. Verbal notice is not enough, follow up in writing, keep a copy, and note the date and who received it.
2. Seek medical care immediately and tell your doctor exactly what happened. Your medical records are the backbone of your claim. Tell your treating physician that the injury occurred at work during a violent incident. Vague descriptions make the insurer's job easier and yours harder.
3. File a DWC-1 claim form. Your employer is required to provide you with this form. Under Cal. Lab. Code §5401, your employer must give you the form within one working day of learning of your injury. Fill it out, keep a copy, and return it.
4. Document the scene and preserve evidence. Photograph your injuries, the location where the incident occurred, and any visible security deficiencies. Get the names and contact information of every witness before you leave. Ask whether surveillance footage exists, it can be deleted quickly.
5. Do not give a recorded statement to the insurer without legal advice. Adjusters ask questions designed to minimize your claim. You are not required to give a recorded statement, and doing so without counsel can harm your case.
6. Contact a workers' comp attorney before accepting any offer. The results we have achieved for injured workers reflect what is possible when every step is handled correctly from the start. A free case review costs you nothing. Accepting the wrong settlement costs you everything.

Frequently Asked Questions
Is a workplace assault covered by workers' comp in California?
Yes. In California, a workplace assault is covered by workers' comp when it arises out of and in the course of employment under Cal. Lab. Code §3600. You do not need to prove your employer was negligent. You need to show that your job placed you in the situation where the violence occurred.
Can I sue a coworker who assaulted me at work?
In most cases, workers' comp is the exclusive remedy against your employer when a coworker injures you under Cal. Lab. Code §3601. However, you may be able to sue the coworker personally in civil court if their conduct was outside the scope of employment. This is a fact-specific analysis. An attorney can help you determine whether a civil claim is viable in addition to your workers' comp claim.
Does workers' comp cover PTSD from a workplace attack?
Yes. Psychiatric injuries including PTSD are compensable under California workers' comp when work was at least 51% responsible for the condition, per Cal. Lab. Code §3208.3. A specific traumatic event, such as an assault, robbery, or active-shooter situation, can satisfy that threshold. Get a psychiatric evaluation promptly so the causal connection to the workplace event is documented in your medical records.
What if my employer did not protect me from workplace violence?
Workers' comp is the exclusive remedy against your employer for your physical injury, even if the employer was negligent about security. You cannot sue your employer in civil court for that negligence. However, if a third-party property owner, security contractor, or other non-employer contributed to the danger, a civil claim against those parties may be available. Document every security failure, broken cameras, ignored threats, inadequate staffing, because that evidence supports both your workers' comp claim and any civil claim against third parties.
What is the deadline to file a workers' comp claim for a workplace violence injury in California?
You have 30 days to notify your employer under Cal. Lab. Code §5400, and one year from the date of injury to file a claim with the WCAB under Cal. Lab. Code §5405. Missing the 30-day reporting window can prejudice your claim. Report in writing immediately after any workplace violence incident.
Can I get both workers' comp and a personal injury settlement for the same workplace assault?
Yes, when the attacker is a third party, not your employer or coworker. You can pursue workers' comp benefits and a personal injury lawsuit simultaneously. Under Cal. Lab. Code §3852, your employer's insurer will have a lien on any civil recovery for benefits already paid, but that lien is negotiable. The combination of both claims typically results in a larger overall recovery than either claim alone.
What should I do right after being attacked at work?
Report the incident to your employer in writing the same day, seek emergency or urgent medical care, tell your doctor the injury occurred at work during a violent incident, photograph your injuries and the scene, collect witness contact information, and preserve any surveillance footage. Do not give a recorded statement to the insurer before speaking with an attorney. Call (818) 794-9947 for a free case review.
