A rule that would have forced most U.S. employers to post a notice of employees' rights under the National Labor Relations Act (NLRA) has been temporarily blocked by a federal circuit court.

The U.S. Circuit Court of Appeals for the District of Columbia on April 17 granted an emergency injunction pending the appeal of a prior D.C. district court ruling that the National Labor Relations Board (NLRB) had authority to issue the poster requirement, but had no ability to punish an employer for failure to comply.
