Sidney Lens explores the history of strikes, from the formation of the first labor unions to the present day. He discusses the conspiracy cases against early unions, the bloody days of the Molly Maguires and the coal miners' strikes, the efforts of the Industrial Workers of the World to use strikes to achieve radical reforms, the growth of large trade unions, and the concessions made by many unions in today's economy. We meet the major figures on either side of the industrial wars that have wracked America – both strikemakers and strikebreakers – as the author examines major strikes that have succeeded and also those that have failed.
