May Day -- International Workers Day -- is rooted in the 19th century battle in the United States to win the 8 hour day for workers, who typically worked 12 and 14 hour shifts, six and seven days a week, under dirty, dangerous, unregulated conditions. Chris Geovanis of Chicago Indymedia provides a snapshot of May Day's history, from the city that gave us the Haymarket Martyrs -- and in many ways served as the birthplace of international workers day.
