U.S. President Donald Trump has fired two Democratic officials at the National Labor Relations Board, a major shakeup that will bring hundreds of cases accusing companies of unlawful labor practices to a standstill and paves the way for Republican control of the agency.

The removal of the National Labor Relations Board’s general counsel had been expected. But the firing of a Democratic member stops it from protecting workers’ rights, for now.

Federal labor law explicitly limits removal of board members to instances of neglect or malfeasance. The termination is among several early moves Trump has made that push at the boundaries of executive authority.

Democratic NLRB member Gwynne Wilcox called her removal “unprecedented and illegal” and vowed to challenge the decision.

It’s been a little more than a week since Inauguration Day, but the seismic shifts of presidential change in Washington, D.C. continue, now extending to and impacting the National Labor Relations Board (NLRB or Board).

U.S. President Donald Trump has fired at least two Democratic members of the Equal Employment Opportunity Commission, which enforces federal laws banning workplace discrimination, in an unprecedented move likely to spur legal challenges.
