On Monday, May 1, hundreds of thousands of immigrants, activists, and     workers of all stripes are expected to take to the streets in cities across     the country and the globe to commemorate International Workers’ Day, aka     May Day.



      May Day’s origins are centered around the call for an eight-hour workday, a     fact of life many of us take for granted but which was fought for fiercely     by industrial workers facing brutal conditions in the late 19th century.     And it was in Chicago, then a rapidly industrializing city, that these     calls reached a fever pitch in 1886, resulting in the violent tragedy of     the              Haymarket Massacre.



      Under these conditions the radical views of socialist and anarchist groups     began to spread throughout American cities, offering more democratic and     humane visions of how society could be organized.



      These proclamations set the stage for the massive strikes that would engulf     the nation on that historic date. More than 35,000 people walked off the     job and              marched          through the streets of Chicago on what is now known as the first May Day     demonstration, part of a nationwide general strike that saw more than     300,000 participants.



      The              red scare          and activist witch hunt that followed did great damage to the labor     movement in the United States, and led to Parsons, Spies, and other     agitators being hung from the gallows. But in many ways the Haymarket     tragedy also set the grounds for May 1 as a worldwide day of action for     workers’ rights.



      The tradition was continued in Chicago in 2006, when more than 500,000 took to     the streets demanding rights for immigrants and undocumented workers in one     of the largest demonstrations in the city’s modern history.
