The next episode in most handbooks is then the introduction of work in a social context; slowly moving away from the rational “scientific” approach of Taylorism and towards a more psychological approach: the employee as a social human being.
One of the most influential research projects which lead to this shift were the so-called Hawthorne Studies, named after a large production site of the Western Electric Company in Chicago, and which took place between 1924 and 1932. The results of the study were not published before 1939 though.

Originally they were a study in the tradition of the taylorist approach; to examine the effects of the length of working hours, the length and frequency of work breaks and the effects of illumination on the productivity.
Especially the results on the effect of illumination were quite surprising. From the present point of view one would expect a brighter work environment would raise motivation and productivity, but in the Hawthorne studies even less light, even to the level of a moonlit night, raised productivity of the experimental group. How could that be ?
This was a difficult one to explain. In several follow-up experiments in which a small group of female workers were isolated and were then put under several working conditions different from that of the main body of workers. They experimented with working hours, light and so on; every time the working conditions changed productivity went up – even when working conditions were less positive. Absenteeism and sickness were also considerable lower in the experimental group.
Researchers concluded that the manipulated conditions could not be responsible for the increase of productivity. It had to be something else. Actually it proved to be the special attention the members of the experimental group received as a group; they felt special and researchers were paying attention to what they were doing. A new experience for them.
Later this effect became known as the Hawthorne-effect: the behaviour of people is influenced by the fact that they know that they are being researched and their interpretation of what is happening around them.
Another Hawthorne study researched the effect of economic rewards on productivity; this took place by observing a group of men which produced a telephone apparatus. This study showed that there are social norms within the group, especially on what is a fair level of production of the group. Employees that did more or less than what they were “supposed” to do, were forced to comply with these social norms. It also showed that there were informal groups within the group.
It proved to be possible to raise production by giving employees a voice to air their complaints on the working conditions and by giving them the impression that they were taken seriously.
And a new movement was born: Human Relations. Also the start of personnel work. In the next version of the Basics: the Human Relations movement.
