California’s Six-Month Rule for Psychiatric Work Injuries: What Counts as Employment?

Review the primary official source.
For a claimed psychiatric injury, California Labor Code section 3208.3 generally requires the employee to have worked for the employer for at least six months. The months need not be continuous. This is a threshold requirement; satisfying it does not by itself prove that the psychiatric condition was caused by work.
The threshold rule
The statute also contains an exception when the psychiatric injury is caused by a sudden and extraordinary employment condition. Courts apply that phrase narrowly. A distressing event is not automatically extraordinary for the occupation, and a worker should not assume the exception applies without analyzing the event and the normal risks of the job.
Calculate employment, not symptoms
Build the employment timeline from payroll records, offer letters, leave records, separation and rehire documents, and actual days or periods worked. Do not calculate six months only from the first symptom, first treatment, or claim filing date. The statutory inquiry concerns employment with the employer.
Interrupted work may still contribute to the total because the statute says the six months need not be continuous. The status of temporary, seasonal, intermittent, or rehired work may require close examination of the actual employment relationship and records.
Keep the exception separate
If employment lasted less than six months, document the specific event alleged to be sudden and extraordinary. Identify when it occurred, who witnessed it, what physical or environmental conditions existed, and how those conditions compared with the worker’s normal duties and industry setting.
A routine workplace dispute, performance meeting, injury mechanism, or traumatic event may be subjectively shocking yet still require proof that it was uncommon and extraordinary in the employment context. Photographs, incident reports, safety records, witness accounts, and job-duty evidence can be more useful than adjectives.
The medical proof is an additional layer
A compensable psychiatric injury requires a diagnosed mental disorder causing disability or a need for medical treatment. The statute also imposes causation standards concerning actual events of employment. Employment duration therefore should not be confused with diagnosis or causation.
Create separate timelines for employment, alleged work events, symptoms, treatment, disability, and notice to the employer. A medical evaluator needs reliable facts about the work events and nonwork contributors. The legal decision cannot rest on a medical label alone.
A disciplined pre-claim checklist
Confirm all periods of employment; collect wage and personnel records; identify the alleged events without exaggeration; preserve pre-incident and post-incident medical records; document notice; and analyze whether another statutory screen, including a personnel-action or post-termination provision, may apply.
Treat the six-month issue as one gate in a larger analysis. That approach is more accurate and more useful than telling a distressed worker that the claim either automatically qualifies or automatically fails based on a rough calendar estimate.

Frequently asked questions
Does a psychiatric claim always require six months of employment?
Section 3208.3 contains a general six-month rule and a sudden-and-extraordinary exception. The employment periods and event must be analyzed carefully.
Can separate periods of work be counted together?
The statute addresses aggregate employment. Payroll, assignment, separation, and rehire records help establish the actual periods.
What should be documented about the claimed event?
Preserve contemporaneous reports, witness information, medical histories, security or incident records, and evidence showing why the event was sudden and extraordinary rather than ordinary working conditions.
