Wal-Mart Stores Inc, known for its strong stance against workers unionizing, closed a tire and lube center in CN recently where workers voted to organize. In August, a Quebec arbitrator imposed a labor contract for tire and lube workers at a Wal-Mart in Quebec. A Wal-Mart spokesman at Wal-Mart 's Bentonville, AR, headquarters confirmed the closing. The United Food & Commercial Workers union called the closure an "attack" on Wal-Mart workers. In 2005 Wal-Mart closed a store in Jonquiere, Quebec, after workers there agreed to unionize. The union has a CN Supreme Court case pending over whether those workers' rights were violated.
