The U.S. Department of Labor offers up a "History of Labor Day":
Labor Day, the first Monday in September, is a creation of the labor movement and is dedicated to the social and economic achievements of American workers. It constitutes a yearly national tribute to the contributions workers have made to the strength, prosperity, and well-being of our country.Labor leaders have had U.S. Navy ships named after them, USS Samuel Gompers and USNS Cesar Chavez.
Have a nice Labor Day Weekend, whether you are a worker or management or even a business owner.
