“The largest U.S. refinery strike in 35 years entered its fourth week on Sunday as workers at 12 refineries accounting for one-fifth of national production capacity were walking picket lines.

Sources familiar with the negotiations said talks may resume by mid-week to end the walkout by 6,550 members of the United Steelworkers union (USW) at 15 plants, including the 12 refineries.”
