Congress will move on two fronts this week to reshape the National Labor Relations Board, the main federal labor law enforcement agency.

The Senate will vote on Peter Robb’s nomination to be the general counsel for the board, while the House will vote on legislation to roll back one of the board’s most controversial moves, its expansion of the “joint employer” doctrine. The board gained a reputation for pro-labor activism during former President Barack Obama’s administration, and the Republicans’ efforts would push it into the role of neutral umpire.
