On this date in 1882, the first Labor Day holiday was celebrated in New York City, in the form of the Labor Day Parade, in accordance with the plans of the Central Labor Union.
The Sept. 5, 1882 parade had nearly 30,000 marchers, who demanded fair working conditions, including the eight-hour work day.
Similar organizations in other cities were urged to have parades as well, in order to show their solidarity with U.S. workers and celebrate a "working man's holiday." The idea spread with the growth of labor organizations, and eventually the first Monday in September was selected as the official holiday.
