May Day, or May 1st, became International Workers' Day in 1886, when it was the beginning of a multi-day general strike in Chicago in which workers demanded an eight-hour work day. On May 4, 1886, the strike ended in what became known as the Haymarket Affair.
Yvonne Geerts of the Immigrant Workers Union said, "In 2006, immigrant workers reclaimed May Day as a clear acknowledgment that immigrants are the first workers who recognize the importance and the practicality of unity with all workers. Today, thousands of working families are victims of the policies of Wisconsin Governor Scott Walker, via service cuts to important programs like BadgerCare, FoodShare, Education, and so much more. Solidarity, today, is more relevant than ever."
