SB 74 amends Michigan's Worker's Disability Compensation Act to clarify how workplace injuries and disabilities are defined and compensated. It specifically modifies rules for mental health conditions (requiring a link to actual work events, not perceptions), refines the definition of "disability" as a limitation in wage-earning capacity, and requires employees to demonstrate good-faith job searches when claiming partial disability. The bill shifts the burden of proof to employers after an employee establishes initial disability, requiring employers to provide evidence to refute claims. These changes directly affect Michigan workers injured on the job and their employers in determining compensation eligibility and benefit amounts.
