In the 1800s, the term journeymen was used to describe skilled industrial workers. These workers joined together to form local labor groups that focused on increasing wages and reducing work hours. They also established the first national labor union, the National Trades' Union, in 1834. Within two years the National Trades' Union had over 300,000 members. This led to the development of other national labor movements that worked to create the 8-hour workday, improve working conditions, stop the use of child labor, and create a national minimum wage.
