In California, Labor Code section 3208 defines "injury" under the California workers' compensation system as any injury or disease arising out of employment. The section 3208 California definition includes specific injuries from a single event and cumulative trauma from repetitive exposure over time — both physical injuries and occupational diseases qualify.
California Labor Code section 3208 defines "injury" under the California workers' compensation system as any injury or disease arising out of and in the course of employment. Under section 3208, the definition is broad — it includes specific injuries from a single identifiable event (a fall, a lifting incident, an explosion, a vehicle collision) and cumulative trauma from repetitive exposure (carpal tunnel, lower-back wear, hearing loss, occupational disease). The section 3208 California definition reaches both physical injuries and occupational diseases; together with California Labor Code §3208.1 California and California Labor Code §3208.3 California, section 3208 establishes the universe of conditions for which California Labor Code §3600 California coverage attaches.
Under California Labor Code section 3208, "injury" includes the full spectrum of industrial harm: specific injuries from a single event such as falls, lifting incidents, machinery accidents, vehicle collisions, and assaults; cumulative trauma from repetitive exposure such as carpal tunnel syndrome, lower-back degeneration, rotator-cuff tears, and chronic occupational disease; occupational diseases such as hearing loss, respiratory disease, and chemical exposure illness; and psychiatric injury subject to the separate California Labor Code §3208.3 California requirements. The section 3208 California definition is broader than the lay understanding and is the gateway to California Labor Code §3600 California coverage.
Under California Labor Code section 3208, the injury categories are distinct. A specific injury has a single identifiable date of injury — the California Labor Code §5400 California 30-day notice and California Labor Code §5405 California one-year filing clock run from that date. A cumulative trauma injury occurs over time through repetitive exposure — the date of injury is determined under the California Labor Code §5412 California "discovery rule" and depends on when the worker became aware of the disability and its industrial cause. The California Labor Code §5500.5 California rule then allocates liability across multiple California employers during the cumulative trauma period.
Under California Labor Code section 3208 (general injury) and California Labor Code §3208.3 (psychiatric injury), the California psych-injury framework imposes additional requirements beyond the general section 3208 definition. Physical injury requires only that the harm arise out of and in the course of employment; California Labor Code §3208.3 California psychiatric injury additionally requires the worker to have been employed for at least six months, the actual events of employment to be the predominant cause (at least 51%), and the injury to fall within DSM-recognized psychiatric diagnoses. The pair distinguishes physical from psychiatric California injury coverage.
Under California Labor Code section 3208, California Labor Code §3600 (AOE/COE no-fault coverage), and California Labor Code §4660 (PD rating), the California coverage and compensation framework operates in sequence. Section 3208 California defines what counts as an "injury"; California Labor Code §3600 California then provides no-fault statutory coverage for injuries arising out of and in the course of employment; California Labor Code §4660 California then rates the permanent disability that resulted. Without a qualifying section 3208 "injury," there is no California Labor Code §3600 California coverage and no California Labor Code §4660 California rating to assign.
