In the mid-19th century, the vast majority of American work was still done on the farm. By the turn of the 20th century, the United States economy revolved around the factory.  The labor movement in the United States grew out of the need to protect the common interest of workers. For those in the industrial sector, organized labor unions fought for better wages, reasonable hours and safer working conditions. The labor movement led efforts to stop child labor, give health benefits and provide aid to workers who were injured or retired.
