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.

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.

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