Members of the House of Representatives, Republicans and Democrats alike, on Thursday called for a swift resolution to the ongoing contract negotiations between shipping companies and West Coast dockworkers, which have tied up operations at the ports of Los Angeles and Long Beach for months. The group representing shippers has called for a halt to ship unloading over the coming three-day weekend, a move dockworkers say is aimed at pressuring them into accepting a deal, the Los Angeles Times reports.
