Labor: collective bargaining; relocation of an employer's operations less than 1 year after its employees elect a bargaining representative; make an unfair labor practice. Amends sec. 23 of 1939 PA 176 (MCL 423.23) & adds sec. 18.

HB 4452 amends Michigan law concerning labor disputes. It introduces a new provision making it an unfair labor practice for an employer to relocate, cease, or subcontract operations within one year after its employees elect a bargaining representative. This means employers would be prohibited from making these specific operational changes shortly after employees unionize. The bill also outlines the process for the labor commission to investigate, hear, and remedy such unfair labor practices.
