In August, the National Labor Relations Board (NLRB) issued a controversial Final Rule that would require most private-sector employers to notify their employees of their rights under the National Labor Relations Act with a new mandatory workplace poster. The rule's effective date originally was November 14, 2011.

Groups like the National Association of Manufacturers, the National Federation of Independent Business, and the U.S. Chamber of Commerce filed lawsuits seeking to block the implementation of the rule's notice-posting requirements. These groups challenged the rule on various grounds, including their position that the rule's notice-posting requirements exceed the NLRB's statutory authority.
