In a major victory for the Coalition for a Democratic Workplace (CDW), the U.S. Court of Appeals for the District of Columbia Circuit granted an injunction to delay the effective date of the National Labor Relations Board’s (NLRB) union poster rule. The poster rule was slated to become effective on April 30, but the effective date has been delayed indefinitely pending the appeals process and decision.

The NLRB poster rule requires most businesses to post an 11-by-17-inch notice in a prominent location explaining the right of workers to join a union and bargain collectively to improve wages and working conditions. The posters also explain that workers have a right not to join a union and that it is illegal for union officials to coerce employees into unionizing.

The DC Appeals Court injunction comes after a federal district judge in South Carolina ruled that the NLRB went beyond its legal authority when issuing the poster rule. That lawsuit was brought last year by the U.S. Chamber of Commerce and the South Carolina Chamber of Commerce.
