1931 and 1932Bank wiring room experiments Workers apparently had become suspicious that their productivity may have been boosted to justify firing some of the workers later on. The study was conducted by Elton Mayo and W. Lloyd Warner between 1931 and 1932 on a group of fourteen men who put together telephone switching equipment.

Broadly speaking, Elton Mayo's management theory promotes the hypothesis that workers are motivated by social and relational forces more than financial or environmental conditions. It holds that managers can increase productivity by treating employees as unique individuals rather than interchangeable cogs in a machine.

Relay assembly test room experiments were designed to determine the effect of changes in various job conditions on group productivity as the illumination experiments could not establish relationship between intensity of illumination and production. For this purpose, the researchers set up a relay assembly test room two girls were chosen.
What is the psychological bond between workers in a group?
