One policy that was continued from the Progressive Era to the New Deal Era was the protection of workers. In the Progressive Era, the National Child Labor Committee was chartered. This government agency investigated potential abuse of child labor and poor working conditions. This agency had the authority to punish businesses who broke certain working laws/standards.
During the New Deal Era (under President Franklin Roosevelt), the Fair Labor Standards Act set a minimum wage and a maximum amount of hours an individual could work in a week. Both of these acts by the federal government were created in hopes to protect workers from potential abuse from their respective bosses.
