Does Workers’ Comp Cover Repetitive-Stress Injuries?
Workers’ comp may cover cumulative injuries from repeated work motions, subject to medical evidence and state causation rules.
California defines cumulative injury as one caused by repeated events or exposures at work, such as repeated wrist motion. Other states use their own rules for causation and claim timing.
Document job duties and exposure over time, and follow the employee’s state reporting deadlines. California advises reporting once the worker knows or believes work caused the condition; check the applicable state’s rule.
