“One of the undesirable by-products of the factory system was the frequent abuse of unskilled workers, including children, who were often subjected to unhealthy working conditions, long hours, and low pay. The appalling conditions spurred a national anti-factory campaign. Led by Mary Parker Follett and Lillian Gilbreth, the campaign gave rise to the “human relations movement" advocating more humane working. Among other things, the human relations movement provided a more complex and realistic understanding of workers as people, instead of merely cogs in a factory machine.”
