In 1916, Sheet and Tube workers at the East Youngstown plant rioted during a strike over working conditions, which resulted in most of the town's business district being burned to the ground. The strike was quelled by the arrival of National Guard troops. After the riots, East Youngstown was renamed Campbell in honor of the company's president. In 1937, Youngstown Sheet and Tube played a prominent role in the Little Steel Strike, along with Republic Steel, Inland Steel, Bethlehem Steel, and Weirton Steel. The so-called "Little Steel" group, led by Republic's Tom Girdler, operated independently of United States Steel, which had previously signed a labor agreement with the Congress of Industrial Organizations (CIO) and its subordinate Steel Workers Organizing Committee (SWOC). Violence during this strike resulted in the deaths of workers in Chicago and Youngstown.
