Striking coal miners in Coeur d’Alene, Idaho dynamite barracks housing Pinkerton management thugs - 1892
And this: July 11, 1892 - Striking coal miners in Coeur d'Alene, Idaho, dynamited the Pinkerton barracks at the Frisco Mill, leaving it in ruins. Pinkerton security guards often were hired by companies to bust strikes and intimidate workers from joining unions.
A nine-year strike, the longest in the history of the United Auto Workers, began at the Ohio Crankshaft Division of Park-Ohio Industries Inc. in Cuyahoga Heights, Ohio. Despite scabs, arrests and firings, UAW Local 91 members hung tough and in 1992 won a fair contract - 1983
