Elton Mayo: Focusing on Human Relations
Elton Mayo (1880-1949), the “Father of the Human Relations Approach,” led the team
which conducted a study at Western Electric’s Hawthorne Plant between 1927 and 1933 to
evaluate the attitudes and psychological reactions of workers in on-the-job situations. The
researchers and scholars associated with the Hawthorne experiments were Elton Mayo,
Fritz Roethlisberger, T.N. Whitehead and William Dickson. The National Research Council
sponsored this research in cooperation with the Western Electric Company. The study was
started in 1924 by Western Electric’s industrial engineers to examine the impact of
illumination levels on worker productivity. Eventually the study was extended through the
early 1930s. The experiments were conducted in four phases:
a. Illumination experiments
b. Relay assembly test room experiments
c. Interview phase
d. Bank wiring observation room experiments

Illumination experiments
These experiments, initiated by Western Electric’s industrial engineers, took place
between 1924 and 1927. These experiments involved manipulating the illumination
for one group of workers (called the experimental or test group) and comparing their
subsequent productivity with the productivity of another group (the control group) for
whom the illumination was not changed. The results of the experiments were
ambiguous. For the test group, performance improved as the intensity of the light
increased. The result was expected. However, the performance of the test group rose
steadily even when the illumination for the group was made so dim that the workers
could hardly see. To compound the mystery, the control group’s productivity also
tended to rise as the test group’s lighting conditions were altered, even though the
control group experienced no changes in illumination (see Figure 2.3). Since there was
a rise in performance in both groups, the researchers concluded that group
productivity was not directly related to illumination intensity. Something besides
lighting was influencing their performance.
At this point of the Hawthorne Experiments, researchers from Harvard University,
under the guidance of Elton Mayo, were invited to participate in conducting the next
phase of experiments.
Relay assembly test room experiments
A second set of experiments took place between 1927 and 1933. In this phase,
researchers were concerned about working conditions such as number of work hours,
frequency and duration of rest periods. The researchers selected six women for the
experiments. These women worked in the relay assembly test room, assembling a
small device called an electrical relay. The participants were informed beforehand
about the experiments. In the course of the experiments, a number of variables were
altered in the room: wages were increased; rest periods of varying lengths were
introduced; the duration of work was shortened. The workers were also granted
certain privileges such as leaving their workstation without obtaining permission.
These workers received special attention from the researchers and company officials.

Generally, productivity increased over the period of the study, regardless of how the
factors under consideration were manipulated. The Harvard University group
ultimately concluded that better treatment of employees made them more
productive. These experiments recognized the importance of social relations among
participants. Since there was no formal supervisor (only the observer was present),
the participants experienced more freedom and a feeling of importance because they
were consulted on proposed changes. The researchers concluded that employees
would work better if management were concerned about their welfare and
supervisors paid special attention to them. One of the findings of the study was the
identification of the concept which came to be described as the ‘Hawthorne effect.’
The Hawthorne effect is defined as the possibility that individuals picked up to
participate in a study may show higher productivity only because of the added
attention they receive from the researchers rather than any other factor being tested
in the study.
Interview phase
During the course of the experiments, about 21,000 people were interviewed over a
three-year period – between 1928 and 1930 – to explore the reasons for human
behavior at work. All the employees in the Hawthorne plant were interviewed. The
generalizations drawn from these interviews are given below:
1. A complaint is not necessarily an objective recital of facts; it can also be a
symptom of personal disturbance, the cause of which may be deep-seated.
2. Objects, persons and events carry social meaning. Their relation to employee
satisfaction or dissatisfaction is purely based on the employee’s personal
situation and how he perceives them.
3. The personal situation of the worker is a configuration of relationships. This
configuration consists of a personal reference and a social reference. While
personal reference pertains to a person’s sentiments, desires, and interests,
social reference pertains to the person’s past and present interpersonal
relations.
4. The position or status of the worker in the company is a reference from which
the worker assigns meaning and value to the events, objects, and features of
his environment, such as hours of work, wages etc.
5. The social organization of the company represents a system of values from
which the worker derives satisfaction or dissatisfaction according to his
perception of his social status and the expected social rewards.
6. The social demands of the worker are influenced by social experiences in
groups both inside and outside the workplace.1[1]
Bank wiring observation room experiments
These experiments were undertaken by researchers to test some of the ideas they
had gathered during the interviews. The experiments were conducted during 1931-
1932.
The fourteen participants in the experiment were asked to assemble telephone wiring
to produce terminal banks. This time no changes were made in the physical working
conditions. In the Bank Wiring Observation Room experiments, workers were paid on
the basis of an incentive pay plan, under which their pay increased as their output
increased. Researchers observed that output stayed at a fairly constant level, which
was contrary to their expectations. Their analysis showed that the group encouraged
neither too much nor too little work. It seemed they had their own idea of what “a fair
day’s work” was and enforced it themselves. The test room participants did not
behave the way the ‘economic man model’ (this model states that employees are
predominantly motivated by money) predicted. Group acceptance appeared to be
more important to the worker than money. Thus, these experiments provided some
insights into informal social relations within groups.

Exhibit 2.3
Limitations of Human Relations Approach
Human relations theory recognizes the significance of human resources. This
theory believes that each individual is unique and the attitude and behavior
of an employee determines the way he or she works. This theory is against
the view that people respond automatically to monetary stimulus. Human
relations theory was one of the greatest advances in management, yet, it did
not succeed in establishing new concepts.
The limitations of the Human Relations theory are:
The Human Relations theorists are of the opinion that by removing
fear, people would perform effectively. This view attacked the
assumption that workers can be motivated to work only through
fear. The Human Relations approach made a significant contribution
at a time when it was generally being assumed that workers have to
be coerced to work. Yet, this approach has very little to say about
positive motivation. The positive motivation aspect has been
generalized by the Human Relations theorists.
Human Relations theory does not provide enough focus on work. It
emphasizes more on interpersonal relations and on “the informal
group.” Consequently, this approach assumes that a worker’s
attitudes, behavior and effectiveness is predominantly determined
by his relation with his fellow-workers and not by the kind of work he
does.
Human Relations does not understand the economic implications of
organizational problems. Therefore, most of the principles advocated
cannot be applied in the organizational context. Human Relations
theory also tends to be very vague. It stresses on “giving the workers
a sense of responsibility” but hardly tells what their responsibilities
are.
Human Relations theory has made noteworthy contributions to the field of
management. It provides valuable guidance in understanding the employees
and managing them. This theory also states the importance of attitudes and
behaviors in managing the workforce effectively. Human Relations is one of
the foundations on which the building of management is to be built.
Although this theory has given great insights, it has its limitations also. This
theory focuses more on the informal group and is very vague about the
positive motivation aspects.

Contributions of Hawthorne experiments
The Hawthorne experiments, which laid the foundation for the Human Relations
Movement, made significant contributions to the evolution of management theory.
Some of the contributions are illustrated in Table 2.7.
Criticism of Hawthorne studies
The Hawthorne studies have received considerable criticism. They have been criticized
on the following grounds:

Job performance depends on the individual The group is the key factor in job
worker. performance.
Fatigue is the main factor affecting output. Perceived meaning and importance of the
work determine output.
Management sets production standards. Workplace culture sets its own production
standards.

1. The procedures, analysis of findings, and the conclusions reached were found to be
questionable. Critics felt that the conclusions were supported by little evidence.
2. The relationship made between the satisfaction or happiness of workers and their
productivity was too simplistic.
3. These studies failed to focus attention on the attitudes of employees at the
workplace.
