CAMPBELL, Ohio — Sept. 17 marked 48 years since thousands of workers, who were mainly men, did what they did every Monday in the valley. They walked into the Campbell Works of Youngstown Sheet and Tube along the Mahoning River for the early shift.

That day, there was a lot of ribbing over the big game on Monday Night Football between the Cleveland Browns and the Pittsburgh Steelers. The workers held almost evenly divided loyalties with both cities almost equidistant.
