[On March 14], the United Steelworkers reached a tentative contract agreement with negotiators from Shell Oil Co., which has represented Chevron, ExxonMobil and other oil companies affected by the union’s now nearly six-week strike. Even as the strike continues in many workplaces, [this] victory is the hard-won result of careful organizing and some promising collaboration. Beginning on February 1 — after a particularly contentious round of negotiations — an estimated 3,800 workers kicked off a strike action across nine refineries in Texas, California, Kentucky and Washington. As of Thursday’s truce, the strike had grown to include 7,000 workers across 15 refineries, petrochemical and cogeneration plants, including the nation’s largest refinery in Port Arthur, Texas. In total, the United Steelworkers, or USW, represents 30,000 members, and holds leverage over an impressive 64 percent of the United States’ refining capacity.
