Legal Alert: As of April 30, 2012, most private sector employers will be required to post a notice advising employees of their rights under the National Labor Relations Act. (The original effective date was postponed.) The notice should be posted in a conspicuous place, where other notifications of workplace rights and employer rules and policies are posted. Employers also should publish a link to the notice on an internal or external website if other personnel policies or workplace notices are posted there.
