Subdivision (d) says no comp is paid for a mental health injury unless the employee has worked for that employer for at least six months. The six months need not be continuous. The rule does not apply if the injury is caused by a sudden and extraordinary work condition.
What the Six-Month Rule Means
The six-month rule is a gatekeeping rule. It asks one first question. Did the worker have at least six months with that employer before the mental health injury date? If not, the claim may fail unless a shock-event exception fits.
The rule is not the whole case. A worker also needs a real mental health diagnosis. The worker also needs proof that actual job events caused the condition. For most claims, work must be the main cause when all causes are compared. For a violent act, or direct exposure to a significant violent act, the statute uses a lower substantial-cause test. That means at least 35 to 40 percent of all causes combined.
How the Rule Comes Up in a Claim
The first fight is often the injury date. A single trauma may have one clear date. A stress injury that built up over time can be harder. The date may depend on when disability began and when the worker knew the condition was tied to work. That date is then compared to the worker's total time with the employer.
The next issue is how the work time is counted. The statute says the six months do not need to be in one unbroken stretch. A worker who left and later returned may still have enough time. The periods must be with the same employer and must add up. Payroll records, hire letters, schedules, and separation papers can help.
The exception is a separate issue. A sudden and extraordinary employment condition is not normal job stress. It is not ordinary discipline, criticism, a busy shift, or a common workplace conflict. It is an event that is unexpected and unusual for that job. Examples may include an assault, a severe accident, a robbery, or a crisis far outside normal job risks. The facts and the medical record decide how strong the argument is.
What Evidence Usually Matters
A mental health injury claim needs more than a worker's own stress story. The medical record should name a diagnosis. It should explain how work events caused the condition. The parties may use a treating doctor, a Qualified Medical Evaluator, or an Agreed Medical Evaluator.
The doctor should sort work causes from non-work causes. Non-work causes can include family stress, prior trauma, illness, or unrelated life events. This sorting matters because the statute asks how much of the condition came from actual events at work.
The employer or insurer may also raise the good-faith personnel action defense. In plain English, this defense can apply when lawful and fair job actions caused most of the injury. Examples can include discipline, reviews, transfers, or attendance rules. The party raising that defense has to prove it. A worker can still point to other real job events that were not personnel actions.
Claims Filed After Job Loss Notice
The statute has extra limits when the worker files after notice of termination or layoff. These limits apply when the claimed injury happened before that notice. In that setting, the worker usually needs the same main-cause proof plus one listed exception.
Examples include employer notice of the injury before job loss notice, medical records showing prior treatment, a qualifying shock event, or a harassment finding by a trier of fact. Timing matters. A worker should report symptoms, get care, and keep records when a work-related mental health injury appears. Late reporting can give the insurer more arguments, especially after job separation starts.

Tap to call →California WCAB Context
This is a statewide California workers' compensation rule. It is not a city rule. The same threshold can arise in cases assigned to WCAB district offices across Southern California. Those offices include Van Nuys, Los Angeles, Long Beach, Bakersfield, Pomona, Riverside, San Bernardino, and Oxnard.
The practical issues are often the same. Prove the diagnosis. Prove the work events. Count the job time. Answer any exception or defense with records instead of guesses.
These claims use many documents. Helpful records can include incident reports, witness names, schedules, prior medical records, mental health notes, termination notices, and written complaints made before job separation. Workers should not rely only on memory when the law requires a timeline.
Frequently Asked Questions
Does the worker need six straight months on the job?
No. The six months do not need to be continuous. Separate periods with the same employer may count. The dates should be backed up with payroll, hiring, and separation records.
What counts as a sudden and extraordinary employment condition?
It must be more than ordinary work stress. A violent assault, a serious workplace accident, or a shocking event outside the usual job risks may qualify. The facts matter. So does what the job normally involved.
Is ordinary workplace stress enough for a mental health claim?
Ordinary stress alone is usually not enough. The worker needs a recognized diagnosis. The worker also needs medical proof that actual job events caused the condition. For most claims, work must be the main cause.
What happens if the claim is filed after termination notice?
Extra limits may apply. The worker may need to show main work cause and fit within a listed exception. Examples include prior employer notice, prior treatment records, a shock event, or a qualifying harassment finding.
Can the employer rely on a personnel action defense?
Yes, if the employer proves the injury was largely caused by a lawful, not discriminatory, good-faith personnel action. The worker can still dispute the facts. The worker can also point to other job events that caused the injury.
What should a worker gather before calling a lawyer?
Helpful items include the hire date, last day worked, injury date, treatment records, incident reports, witness names, written complaints, personnel notices, and any denial letter. A short timeline is a useful starting point.
