Labor Day, the holiday celebrating the contributions of workers to the fabric of American life, is Monday, Sept. 1.
The holiday was first celebrated in New York City in 1882. As unions expanded throughout the nation, Labor Day events grew in popularity, and in 1894, President Grover Cleveland signed the bill declaring the first Monday in September a federal holiday.
The Postal Service has more than 640,000 workers.
The U.S. Department of Labor’s website has a history of the holiday, describing it as a tribute “to the creator of so much of the nation’s strength, freedom, and leadership — the American worker.”
