From the NLRB:
The National Labor Relations Board has agreed to postpone the effective date of its employee rights notice-posting rule at the request of the federal court in Washington, DC hearing a legal challenge regarding the rule. The Board’s ruling states that it has determined that postponing the effective date of the rule would facilitate the resolution of the legal challenges that have been filed with respect to the rule. The new implementation date is April 30, 2012.
Merry Christmas!
