In the 1920s, Western Electric Company ordered a series of studies to be conducted at their plant in Cicero, Illinois. At first they wanted to see how lighting affected productivity on the factory floor. Researchers also interviewed employees to hear their ideas and opinions about company policies, management, and other subjects. These were the Hawthorne studies, landmark research in industrial and organizational psychology. In the early 1970s, some of the participants of this study—researchers and workers alike--reunited and reminisced about their involvement.
