In response to a 28-percent wage cut, 4,000 Pullman Palace Car Company workers went on strike in Illinois, bringing rail traffic west of Chicago to a halt.

The Pullman Company, founded by George Pullman, was a manufacturer of railroad cars in the mid-to-late 19th century through the first half of the 20th century, during the boom of railroads in the United States. Through rapid late-19th century development of mass production and takeover of rivals, the company developed a virtual monopoly on production and ownership of sleeping cars.

The Pullman Strike comprised two interrelated strikes in 1894 that shaped national labor policy in the United States during a period of deep economic depression. First came a strike by the American Railway Union (ARU) against the Pullman Company's factory in Chicago in spring 1894. When it failed, the ARU launched a national boycott against all trains that carried Pullman passenger cars. The nationwide railroad boycott that lasted from May 11 to July 20, 1894, was a turning point for US labor law. It pitted the American Railway Union (ARU) against the Pullman Company, the main railroads, the main labor unions, and the federal government of the United States under President Grover Cleveland.
