Philip Miscimarra, the new chairman of the National Labor Relations Board, is poised to be the Antonin Scalia of workplace law, business and labor experts say. Like the late Supreme Court justice, he believes that the only thing that matters is what the text of the law explicitly says.

Also like Scalia, he has penned a string of vigorous, sometimes acerbic dissents to his colleagues’ rulings. He will have the opportunity to roll back the board’s recent, mainly pro-union changes now that President Trump has put him in charge of the nation’s main federal labor law enforcement agency – a prospect that has business groups cheering and labor advocates gloomy.
