The Great Railroad Strike of 1922, commonly known as the Railway Shopmen's Strike, was a nationwide strike of railroad workers in the United States. Launched on July 1, 1922, by seven of the sixteen railroad labor organizations in existence at the time, the strike continued into the month of August before collapsing. A sweeping judicial injunction by Judge James Herbert Wilkerson effectively brought the strike to an end on September 1, 1922.
