Since 2017, Republican appointees have firmly controlled the National Labor Relations Board. Not surprisingly, the agency has released a slew of decisions markedly reducing or eliminating union rights.
One of the most egregious is MV Transportation, issued in September 2019. This decision upended 70 years of NLRB law requiring employers to give advance notice and bargain with unions before making substantial mid-contract changes to rules, policies, and practices not fixed by the contract. Attendance requirements, safety policies, and subcontracting unit work are typical examples.
