Today in labor history, July 24, 1877: The first general strike in U.S. history is underway in St. Louis. Led by members of the Workingmen’s Party, it began as an outgrowth of the railroad strike sweeping the country. Workers – skilled and unskilled, black and white – shut down the city for a week until thousands of federal troops and special deputized police arrived, killing at least eighteen people and arresting the strike leaders.
