Remember Haymarket - Workers Unite!

May 1st is May Day, the international workers' holiday honoring the labor movement. May Day is celebrated in at least 80 countries worldwide, from Argentina to Vietnam, but not in the United States. Here, our "Labor Day" was carefully put into September – by President Grover Cleveland in 1894 – specifically so that we would not observe May Day, with all of its radical roots in syndicalist labor history. This is deeply ironic, for the event that gave rise to May Day observances the world over occurred right here in the United States: the bombing at Haymarket Square, Chicago, on May 4, 1886, during a labor rally.

The context for the Haymarket riot in 1886 was the movement for the eight-hour work day.

During the Second Red Scare, it was recognized by the U.S. Congress on April 27, 1955, and made an official reoccurring holiday on July 18, 1958 (Public Law 85-529). President Dwight D. Eisenhower proclaimed May 1, 1955, the first observance of Loyalty Day.In 1958, Eisenhower urged Congress to move Child Health Day to the First Monday in October, to avoid conflicting with Loyalty Day Loyalty Day has been recognized with an official proclamation every year by every president since its inception as a legal holiday in 1958.
