The U.S. National Labor Relations Board has adopted a rule change that would streamline union-forming elections and delay the appeals process. In response, the U.S. Chamber of Commerce filed a lawsuit...to halt the rule...Supporters of the new rule say it will reduce unnecessary litigation and delays in the election process...[The Chamber's] complaint [claims]...that the rule “curtails an employer’s right to communicate with its employees by substantially shortening the election period”...AFL-CIO president Richard Trumka said the board took a “modest but important step” with the passage of the rule, but said that “many more improvements are needed to protect workers’ rights.”
