Labor Day is a federal holiday in the United States celebrated on the first Monday of September to honor and recognize the American labor movement and the contributions of workers to the country's development and achievements
. It originated in the late 19th century as a response to harsh working conditions, long hours, and the need for fair wages and safer workplaces. The first Labor Day parade was organized in New York City in 1882 by labor unions such as the Knights of Labor, and by 1894 it became a national holiday signed into law by President Grover Cleveland
. The holiday celebrates the social and economic achievements of workers and the labor movement, reflecting decades of struggle for better working conditions, including the fight for an eight-hour workday
. While it has evolved into a day often associated with picnics, parades, and the unofficial end of summer, its roots lie in honoring laborers' rights and contributions
. Internationally, many countries celebrate workers on May 1st, known as International Workers' Day or May Day, which commemorates labor strikes and events such as the Haymarket affair in Chicago in 1886
. However, the U.S. Labor Day was established in September partly to avoid association with the more politically charged May Day celebrations
. In summary, Labor Day is about recognizing and honoring the historic and ongoing contributions of workers and the labor movement to society, celebrating their achievements in improving working conditions and labor rights
