Labor Day in the United States commemorates the labor movement's achievements and honors the contributions of workers to the nation's economy. Initially celebrated in the late 19th century, Labor Day became a federal holiday in 1894, intended to acknowledge the struggles of workers who fought for better working conditions, fair wages, and the right to unionize. The holiday is observed on the first Monday in September and symbolizes the end of summer, often marked by parades, picnics, and family gatherings. It serves as a reminder of the enduring principles of workers' rights and the ongoing quest for justice in the workplace.
