The Hawthorne studies helped conclude that workers were highly responsive to additional attention from their managers and the feeling that their managers actually cared about, and were interested in, their work. The studies also concluded that although financial motives are important, social factors are equally important in defining the worker productivity.
There were a number of other experiments conducted in the Hawthorne studies, including one in which two women were chosen as test subjects and were then asked to choose four other workers to join the test group. Together, the women worked assembling telephone relays in a separate room over the course of five years (1927–1932), and their output was measured. The measuring began in secret. It started two weeks before moving the women to an experiment room and continued throughout the study. In the experiment room, they had a supervisor who discussed changes with them and, at times, used their suggestions. The researchers then spent five years measuring how different variables impacted both the group's and the individuals' productivity. Some of the variables included giving two five-minute breaks (after a discussion with the group on the best length of time), and then changing to two 10-minute breaks (not the preference of the group)..
