Our friends at the California Chamber of Commerce just let me know that the U.S. District Court for the District of South Carolina held in Chamber of Commerce v. NLRB (opinion here) that the NLRB did not have authority to require employers to post a poster informing employees of their rights under the National Labor Relations Act. (Poster information here and here.) A district court previously held the NLRB did have the authority to require the poster, but did not have the power to create a new "unfair labor practice" when employers do not comply. See National Ass’n of Manufacturers v. NLRB, No. 11-1629, 2012 WL 691535 (D.D.C. Mar. 2, 2012) (opinion here).
So, this is going to shake out in the Courts of Appeals or the U.S. Supreme Court. Perhaps the Board will "delay" the implementation date again. Stay tuned.
