Wal-Mart Watch: A Las Vegas judge issues a split decision, upholding Wal-Mart firing of a worker for union activity but condeming Wal-Mart's other anti-union tactics: Parke also ruled that Wal-Mart managers violated the National Labor Relations Act by "impliedly telling employees to destroy or disregard union literature and taking union literature away from employees" at the Marks Street store in Henderson. So Wal-Mart gets the standard NLRB penalty: Parke ruled that notices must be posted at the Marks Street store stating that workers have the right to organize and that the right is protected by federal law. The notices are to be posted for 60 days. That's a rough measure, unfortunately, of how seriously the legal system in this country takes the exploitation of workers.
