Worker's compensation: benefits; type of employee misconduct that excludes an injured employee from receiving benefits; modify. Amends sec. 305 of 1969 PA 317 (MCL 418.305).

HB 5183 amends Michigan's Worker's Disability Compensation Act (MCL 418.305) to clarify when an injured worker loses benefits due to their own misconduct. The bill states that an employee cannot receive benefits if their employer proves the injury resulted from the employee's "intentional, serious, and wilful misconduct." It defines "serious" misconduct as objectively egregious and harmful conduct that endangers the employee or others. This change directly affects injured workers whose employers claim they caused their own injury through severe workplace misconduct. The bill is currently in committee referral after its introduction on October 30, 2025.
