The National Labor Relations Board (NLRB), stung by various court rejections of its National Labor Relations Act (NLRA) poster detailing employee rights in the workplace, has taken its cause to the world of smartphones, unveiling an app on Labor Day Weekend spelling out employer obligations and employee protections.

“The promise of the law can only be fulfilled when employers and employees understand their rights and obligations,” NLRB Chairman Mark Pearce said in a statement.  The agency received more than 82,000 public inquiries last year about workplace issues, and “this app can help provide the answers,” he said.

The app, available on Google Play and the Apple App Store, will be promoted on the NLRB home page, Facebook and Twitter.

The introduction of the app comes at the close of a dayslong celebration of NLRA Week across the country by the agency.
