There are many federal and state posting obligations.  You can now add another poster to the list.  As of April 30, 2012, most private sector employers will be required to post an 11 x 17 inch notice from the National Labor Relations Board that advises employees of their rights under the National Labor Relations Act.  The Board originally set a deadline of January 31, 2012, but that was extended to April 30.  A copy of the poster is available at no cost from the Board through its website, www.NLRB.gov.  The National Association of Manufacturers and others brought suit and challenged that Board’s posting requirement.  On March 2, 2012, Judge Amy Berman Jackson of the United States District Court for the District of Columbia issued a ruling upholding the Board’s rule requiring the poster, but she struck down a portion of the rule regarding enforcement.  Several of the plaintiffs submitted notices that they intend to appeal the decision and have moved to stay enforcement of the rule during the appeal.  Stay tuned.
