The first official Labor Day parade in Washington, D.C., September 5, 1894, marches along Pennsylvania Avenue past the nearly completed Post Office Building. |
Labor Day in the United States traces its roots to the late 19th century, when the nation was undergoing rapid industrialization. Factories, railroads, and mines relied on long hours of grueling work, often in unsafe conditions, for meager pay.
In response, labor unions began organizing strikes and rallies to demand better wages, shorter hours, and safer workplaces. The first Labor Day observance took place on September 5, 1882, in New York City, organized by the Central Labor Union.
Thousands of workers marched in a parade, followed by a picnic and speeches, to demonstrate solidarity and celebrate the dignity of labor.
Over the next decade, similar events spread to other cities, propelled by union activism and public support for workers’ rights. The push for a national holiday gained momentum after the Pullman Strike of 1894, a bitter railway labor conflict that led to federal troop intervention and violent clashes.
In an effort to ease tensions and honor the contributions of American workers, Congress quickly passed legislation designating the first Monday in September as Labor Day. President Grover Cleveland signed it into law on June 28, 1894. Today, Labor Day serves both as a tribute to the labor movement’s achievements and as the symbolic end of summer—a day for parades, barbecues, and reflection on the enduring role of workers in shaping the nation.
The then new Post Office in Washington, D.C., was completed in 1899 after five years of construction, serving as the city’s main post office and headquarters for the U.S. Post Office Department.
Designed in the Romanesque Revival style by architect Willoughby J. Edbrooke, its 315-foot clock tower made it the tallest structure in the capital at the time. Though its massive granite façade and ornate detailing reflected the grandeur of the era, the building’s location and layout quickly became outdated for postal operations, leading to its eventual decline in use and decades of debate over its preservation--thus it became the Old Post Office building and tower.
