Summary of California’s Workers’ Compensation Landscape

California operates a mandatory no-fault workers’ compensation system covering medical care, temporary disability, permanent disability, and supplemental job displacement benefits.

  • Reporting Deadline: Employees must report injuries to employers within 30 days of the injury (or when they became aware it was work-related).
  • Authorized Medical Care: Controlled initially by the employer’s Medical Provider Network (MPN) if one is established, unless the employee pre-designated their personal physician prior to the injury.
  • Wage Replacement: Temporary Disability (TD) benefits provide two-thirds of the injured worker’s average weekly wage (subject to state-mandated minimum and maximum caps).
  • Key Deadlines & Limits:
    • 30 Days: To report the injury to the employer.
    • 104 Weeks: Maximum limit for temporary disability payments within a 5-year window from the date of injury for most conditions.
    • 1 Year: Statute of limitations to file an official Application for Adjudication of Claim with the WCAB if benefits are denied.
