The National Labor Relations Board drew criticism for its “microwave” rule vote in November. Opponents say the provision doesn’t allow employers enough time to discuss unionization with employees.

It’s the latest action by the board that has peeved business groups. The measure attempts to simplify union election procedures and reduce the deadline for holding them after employees request a vote.

While groups such as the National Association of Manufacturers blasted the vote as creating “ambush elections,” NLRB Chairman Mark Pearce countered that the new proposal “seeks to avoid multiple and unnecessary appeals in union elections, and does away with unnecessary waiting periods.”

ALFA President and CEO Richard P. Grimes said the organization supports House GOP efforts to curb a “labor board agenda.”

“The NLRB continues to advance a radical agenda through proposed rules and recent decisions,” he said.

The rule will be drafted into final language for a subsequent NLRB vote before it goes into effect. As expected, the 2-1 vote was along party lines, with the lone Republican member dissenting.
