Contributions of the Human Relations and Behavioural Science approach

How the approach arose

The paper speaks of a single Human Relations and Behavioural Science approach. It is read here as the neo-classical line of thought taken as a whole, with two connected strands: the human relations school and the behavioural science approach that grew from it. Both reacted against the classical writers. Taylor's scientific management looked for the one best way of doing a job, and Fayol's administrative principles looked for the best way of combining jobs and people into an efficient structure, while the classical view as a whole assumed that people are moved mainly by economic gain. The neo-classical writers kept much of that machinery but asked a different question: what happens to the people inside it?

Contributions of the Human Relations studies

The human relations school took shape between the 1920s and the 1950s. Its central finding was that employees do not respond rationally only to rules, chains of command and economic rewards; they are also moved by social needs, drives and attitudes. The Hawthorne Studies belong to this period, and the school's distinctive mark was the attention it gave to the human factor at a time when management had been preoccupied with techniques and technology. Its main contributions to managerial thought were these:

1. Group behaviour and group norms. A person in a group does not behave as he or she would alone. Elton Mayo's work in the Hawthorne Studies found that workers follow the norms their group sets, so output depends on the group's attitude as well as on each worker's ability.
2. The informal organisation. Besides the formal structure, employees form informal relationships among themselves, and the manager has to take these into account rather than pretend they do not exist.
3. Management works with and through people. Efficiency improves when the manager adds a human approach to the scientific one, because results come from people and not only from methods.
4. Social needs as motivators. Recognition, belonging and attention matter to workers alongside wages, so a manager who looks only at pay misses much of what drives effort.

In practice this means that a supervisor in a Ludhiana garment unit who wants higher output gains more by winning over the informal leaders of each production line than by issuing orders to workers one at a time.

Contributions of the Behavioural Science writers

The human relations school prepared the ground for the behavioural sciences. Writers such as Chris Argyris, Douglas McGregor, Abraham Maslow and Frederick Herzberg drew on psychology, sociology and anthropology, and their underlying view, called organisational humanism, is that people need to use all their capacities and creative skills at work as much as at home. Three contributions stand out:

1. The hierarchy of needs. Maslow arranged human needs in five ascending levels, beginning with basic physiological needs and safety and rising through belonging and esteem to self-actualisation. As the lower needs are met, a person looks to the higher ones; while a basic need is unmet, it takes priority.
2. Two kinds of job factors. Herzberg separated the factors that make people satisfied from those that make them dissatisfied. Satisfiers, or motivators, lie in the job's content: achievement, recognition, advancement, responsibility, growth and the work itself. Dissatisfiers, or hygiene factors, lie in its context: company policy, supervision, pay, job security, working conditions and relations with others. Better pay or canteens may remove complaints, but lasting motivation comes from the job itself.
3. Assumptions about people. McGregor showed that management practice rests on assumptions about human nature. Theory X assumes that work is distasteful, that most people avoid responsibility and must be closely controlled. Theory Y assumes that work can be as natural as play, that creativity is widely spread and that people can direct and control themselves when properly motivated. A manager who holds Theory Y assumptions delegates, consults and trusts; one who holds Theory X assumptions supervises closely.

Combined contribution to managerial thought

Together the two strands changed what a manager is expected to do. Management came to be seen as working with and through people, with a human approach added to the scientific one, and the human factor moved to the centre of managerial thought. Motivation, group relations and the use of each person's abilities became part of the manager's job. A Bengaluru software firm that lets engineers own whole features, recognises good work in team meetings and leaves routine supervision to the teams themselves is applying this line of thought.

Limitations

The behavioural theories describe general tendencies, not fixed laws. Herzberg himself outlined only a general tendency: a factor that dissatisfies one employee may satisfy another. McGregor's two theories are not a simple choice of good over bad either, since no two people or situations are alike and even a Theory Y manager may supervise some employees closely for a time until they are ready for more freedom. The approach therefore supplies insight into people rather than ready-made answers, and the manager still has to judge each situation.

Conclusion

The Human Relations and Behavioural Science approach did not replace the classical school; it completed it. By putting the human being at the centre of management, it made motivation, groups and the full use of people's abilities part of every manager's work, and later schools built on that foundation.
