Labor Day exists to honor and recognize the American labor movement and the contributions of workers to the country's development and achievements. It was established as a national holiday in 1894 by Congress, with roots tracing back to the late 19th century labor movement, including the first Labor Day parade in New York City in 1882 and the labor struggles during events like the Haymarket Riot of 1886. The holiday reflects the efforts of workers to secure better working conditions, shorter hours, and fair wages, and it remains a day to celebrate workers' achievements and solidarity.
