Labor Day is celebrated to honor and recognize the American labor movement and the contributions of workers to the development and achievements in the United States. It originated in the late 19th century when workers faced extremely difficult working conditions, including long hours and unsafe environments. Labor Day was first celebrated with parades and rallies organized by labor unions, notably starting in New York City in 1882, and it became a federal holiday in 1894. The holiday emerged as a way to acknowledge workers’ rights and their role in building the country after years of labor struggles, including strikes and demands for an eight-hour workday. Labor Day is observed on the first Monday of September in the U.S., symbolizing a tribute to the social and economic achievements of American workers. This contrasts with International Workers' Day (May Day) celebrated in many other countries, which commemorates workers' rights with roots in events like the Haymarket Affair in Chicago in 1886. Overall, Labor Day serves as a day of rest, parades, speeches, and celebrations recognizing the power and achievements of labor unions and workers in improving working conditions and standards of living.
