In California, a worker can claim a psychological injury under §3208.3 — but the rules are strict. Generally six months of employment are required, the work must be the predominant cause of the injury, and good-faith personnel actions are excluded. Yazdchi Law, a Certified Specialist in Workers' Compensation Law firm, handles California psych claims.
For a California worker whose job has caused real psychological harm — chronic anxiety, depression, post-traumatic stress, panic disorder — the question of whether to file a workers' compensation claim is fraught. The injury is real, but the worker often doubts whether it "counts," whether the doctor will be believed, and whether the employer will retaliate. California law does recognize psychological injuries as compensable — but the framework is stricter than for physical injuries, and the procedural rules are unforgiving.
This guide walks through California's psychological injury framework under California Labor Code §3208.3: the basic requirements, the six-month employment threshold, the "predominantly" work-caused standard, the exclusion for good-faith personnel actions, and the unique medical-legal evidence required for psych claims. It is written for a worker considering whether to file a stand-alone psych claim or to add a psych component to an existing workers' comp case.
The short version: California psych injuries are compensable under California Labor Code §3208.3, but with three significant gates. First, the worker generally needs at least six months of employment with the employer before filing a stand-alone psych claim. Second, the actual work events must be the predominant cause (more than 50%) of the injury. Third, good-faith personnel actions — performance reviews, layoffs, lawful discipline — are generally excluded from the causation analysis.
Under California Labor Code §3208.3, a workers' compensation claim for a psychiatric injury requires the worker to demonstrate, by a preponderance of the evidence, that actual events of employment were the predominant cause of the injury. The statute also includes several procedural and substantive gates that distinguish psych claims from physical-injury claims under California Labor Code §3208.1.
The basic compensability question for a psych claim has three parts. First, was there a diagnosable psychiatric injury under recognized medical standards? Second, were actual events of employment the predominant cause (more than 50%) of the injury? Third, do any of the statutory exclusions apply — particularly the good-faith personnel action exclusion?
Under California Labor Code §3208.3, a worker generally must have been employed by the employer for at least six months before filing a stand-alone psychiatric injury claim. The six-month threshold does not apply when the psychiatric injury is caused by a "sudden and extraordinary employment condition" — for example, a workplace assault, a robbery, a fire, a serious physical injury, or witnessing a coworker's serious injury or death. In those cases, the six-month requirement is waived.
The six-month threshold also does not apply to psychiatric injuries that are added to (or grow out of) a compensable physical injury — for example, depression following chronic pain from a back injury, anxiety following a serious workplace fall, or PTSD following a serious accident. In those "compensable consequence" psych claims, the underlying physical injury supports the psych component without the six-month threshold.
Under California Labor Code §3208.3, the worker must show that actual events of employment were the predominant cause of the psychiatric injury — meaning more than 50% of the cause when considering all sources combined (work-related, family, personal, financial, prior history). This is a higher causation bar than the "any work-related cause" standard that applies to physical injuries under California Labor Code §3208.1.
The "predominantly" standard plays out in the QME or AME report under California Labor Code §4062.2. The psychologist or psychiatrist evaluates the worker's history, the work events alleged to have caused the injury, any non-industrial stressors, and the medical evidence (treatment records, diagnostic findings under recognized standards). The medical-legal opinion specifically allocates causation among the various stressors — and the work cause must exceed 50% for the claim to be compensable.
Under California Labor Code §3208.3, a psychiatric injury is generally not compensable if it was substantially caused by a lawful, non-discriminatory, good-faith personnel action by the employer. The exclusion covers performance reviews, lawful disciplinary actions, layoffs, promotions or denials of promotion, transfers, schedule changes, and other ordinary employment decisions. The exclusion exists to prevent every workplace personnel decision from generating a psych claim.
The exclusion does not cover unlawful, retaliatory, discriminatory, or harassing personnel actions. A demotion in retaliation for filing a workers' comp claim under California Labor Code §132a, a hostile workplace environment based on protected characteristics, or harassment outside the bounds of lawful employer authority can support a psych claim. The good-faith requirement matters — a personnel action that on its face looks ordinary but was actually motivated by retaliation under California Labor Code §132a is not "good faith" for §3208.3 purposes.
California psych claims commonly arise from several event patterns. First, workplace violence — assaults, robberies, threats, weapons in the workplace. Second, witnessing serious injury or death of a coworker. Third, chronic harassment, bullying, or hostile work environments outside the good-faith personnel action exclusion. Fourth, severe trauma involving customers, patients, or the public — common in healthcare, law enforcement, social work, and retail. Fifth, compensable-consequence psych following a physical injury — depression, anxiety, or PTSD developing from chronic pain, disfigurement, loss of function, or the workers' comp claim experience itself.
The psych claim follows the same procedural path as any California workers' comp case. The DWC-1 is filed; the §5402(b) 90-day decision window applies; medical treatment under California Labor Code §4600 begins with a qualified psychiatrist or psychologist (in the MPN under California Labor Code §4616 or with a predesignated mental health provider). The QME or AME process under California Labor Code §4062.2 produces the medical-legal report addressing diagnosis, causation, and apportionment under California Labor Code §4663. Maximum Medical Improvement and the permanent disability rating under California Labor Code §4660 apply using the AMA Guides 5th Edition Chapter 14 (mental and behavioral disorders) and the Global Assessment of Functioning. Settlement is by Compromise and Release under California Labor Code §5001 or Stipulation under California Labor Code §5003. An adverse Findings and Award can be challenged under California Labor Code §5903 within 25 days of service by mail (or 20 days from electronic service).

Tap to call →California psychological injuries are real, compensable, and frequently under-claimed. The framework under California Labor Code §3208.3 is stricter than for physical injuries — the six-month threshold, the predominant-cause standard, and the good-faith personnel action exclusion all narrow the field. But for workers whose work has actually caused diagnosable psychiatric harm, the path is real.
Psych claims live or die on the specificity of the work events. Vague "the job was stressful" claims rarely succeed; specific accounts of identifiable events — the workplace assault on a date, the witnessing of a coworker's injury, the chronic harassment with names and dates — support the predominantly-work-caused standard under California Labor Code §3208.3. Contemporaneous records (emails, journals, complaints to HR) strengthen the case.
The medical-legal record needs a diagnosis under recognized standards (typically DSM-5 criteria), a treatment plan, and a causation opinion specifically allocating work and non-work causes. A treating psychologist or psychiatrist under California Labor Code §4600 (in the MPN under California Labor Code §4616) lays the foundation; the QME under California Labor Code §4062.2 or AME finalizes the medical-legal opinion. The provider's causation language is critical to meeting the predominant-cause standard.
California workers' compensation attorneys work on contingency under California Labor Code §4906 — typically 15% of any settlement, paid only if the case recovers. A free consultation costs nothing, and a Certified Specialist in Workers' Compensation Law, certified by the California Board of Legal Specialization, State Bar of California, can evaluate the §3208.3 thresholds, the medical-legal strategy, and the personnel-action exclusion question.
