Since Election Day, unions have lived on borrowed time. The NLRB is still controlled by Democrats — thus shielding workers and their unions from attacks that became far likelier the moment Donald Trump was declared the winner of the 2016 election. But this period of interregnum is about to end. Mitch McConnel began the process of confirming the first of Trump’s two nominees to the NLRB on Monday. When both nominees sit on the Board, a swift rollback of union rights is likely.In recent years, however, the Board has grown increasingly partisan. By design, it has five board members, and three of those seats are typically controlled by the party that also controls the White House. For this reason, the Board’s understanding of labor law often lurches to the left and then to the right as control of the presidency changes hands."
