The Globe and Mail reports in its Wednesday edition that B.C. port workers returned to the picket lines instead of reporting for their scheduled night shifts on Tuesday after their union leadership rejected a tentative four-year deal announced last week. The Globe's Brent Jang writes that the International Longshore & Warehouse Union Canada halted its 13-day strike on Thursday, but the resumption of work was short lived. The ILWU listed contracting out as one of its three main issues. The union sought a two-year agreement, while employers proposed a four-year deal. Business groups warn that it could take until late September or even longer to fully clear the backlog of cargo that has been piling up since Canada Day. Federal Mediation and Conciliation Service director Peter Simpson drafted the recommended collective agreement that led to last week's tentative settlement. "The ILWU Canada longshore caucus does not believe the recommendations had the ability to protect our jobs now or into the future," the union said late Tuesday. The ILWU's caucus that includes representatives of locals rejected the tentative pact that had been given the nod on Thursday by the union's bargaining unit.
