From Washington: Labor Day has its roots in the late 19th century when activists pushed for a day to honor workers. The first celebration in the US took place on September 5, 1882, and featured a parade with 10,000 workers. Most retailers will be open on Labor Day, while government offices, banks, and the stock market will be closed.
