This week, the U.S. Chamber of Commerce and several business trade groups announced that they jointly filed a complaint in federal court against the National Labor Relations Board (NLRB), seeking to strike the Board’s new “ambush” election rule that shortens the period between the filing of a union election petition and the election itself. The NLRB adopted the rule on Dec. 12, 2014 in a 3-2 vote. If not overturned, the rule is set to go into effect on April 14, 2015. See our previous post here.

The complaint alleges that the new rule violates the National Labor Relations Act, the Administrative Procedure Act, and employers’ free speech and constitutional right to due process. Read the press release here.

Joining the Chamber in the lawsuit are the Coalition for a Democratic Workplace (CDW), National Association of Manufacturers (NAM), National Retail Federation, and Society for Human Resource Management (SHRM). Worth noting is that this is only the third time SHRM has challenged a federal regulation in court.
