As promised, the U.S. Chamber of Commerce as filed a lawsuit against the U.S. National Labor Relations Board (NLRB) over the recent decision to shorten the timeframe between filing a petition and holding an election. Hence, the name “ambush election.”

According to the chamber’s lawsuit: “The rule violates the National Labor Relations Act and the Administrative Procedure Act, as well as employers’ free speech and due process constitutional rights. In particular, the lawsuit challenges the Board’s rule as impermissibly limiting employers’ rights to communicate with employees about unionization by dramatically shortening the period between the filing of a union election petition and the holding of the election itself.”
