WWU, a project of the Change to Win union federation, has worked in concert with the union-backed retail workers' group OUR Walmart to pull off a series of strikes in the Wal-Mart supply chain since 2012. Workers' lawsuits have represented one front in labor's efforts to hold Wal-Mart accountable for conditions of its suppliers and contractors, which advocates argue are largely determined by Wal-Mart directives. In March, Judge Christina Snyder barred Schneider from communicating with employees about the Quezada suit without permission, on the grounds that it had behaved in "deceptive" and "coercive" ways in securing written statements from employees designed to undermine the plaintiffs' case.
