Answer:
Human Relations Movement
Step-by-step explanation:
The source of the human relations movement is the 1930s' Hawthorne Studies by Dr. Elton Mayo. The approach states that the productivity of employees or subordinates is a product of motivation, satisfaction and social relations all tending towards psychological balance.
The Human Relations Movement sees the employee as a part of the psychology of an organisation and not an easily replaceable part. As such, employees and subordinates should be treated as valuable.
It is based on this view, that it is advocated that supervisors manage their subordinates as valuable parts of the organisation, providing crucial motivation to ensure satisfaction. As such, the supervisors will need to be trained psychologically or behaviourally to be able to handle their subordinates appropriately.
