May 1, 2008 saw tens of thousands of people participate in Chicago Mayday events. The flagship action was a large march starting from Union Park, and marching across Chicago to a rally in Federal Plaza, though many other events were also held.
Two main threads of the march and of the holiday — immigrant rights and labor rights — were more explicitly connected in 2008. The scale of the protest evokes the massive marches and rallies in 2006 and 2007.
