In response to two federal court cases we previously blogged about here and here, the NLRB has indefinitely postponed implementation of its notice posting rule pending appeals in both of those cases. The bottom line is that no employer needs to post the notice for the time being.
The U.S. Court of Appeals for the D.C. Circuit will hear the NLRB’s appeal of an emergency injunction that court issued against the rule, but the hearing will not occur before September 2012. In the trial court ruling in that case, the judge found the NLRB's posting rule valid, but its enforcement provisions invalid. The NLRB is also appealing the South Carolina federal trial court decision we previously blogged about, in which a judge deemed the NLRB's entire posting rule invalid. No schedule has yet been set for the South Carolina appeal.
