A decision by the U.S. Court of Appeals for the District of Columbia (D.C.) Circuit Court has delayed a new rule -- set to take effect April 30 -- that required workplaces to post right-to-organize notices.

To be in compliance with the new rule, private employers will have to post an 11-by-17-in. notice regarding employee rights to unionize under the National Labor Relations Act. The requirement was set by the National Labor Relations Board (NLRB).
