Pullman Strike
"Pullman Strike, (May 11, 1894–c. July 20, 1894), in U.S. history, widespread railroad strike and boycott that severely disrupted rail traffic in the Midwest of the United States in June–July 1894. The federal government’s response to the unrest marked the first time that an injunction was used to break a strike. Amid the crisis, on June 28 Pres. Grover Cleveland and Congress created a national holiday, Labor Day, as a conciliatory gesture toward the American labor movement."
