At the Diwali time, Gupta Bros., leading manufacturers of gift items, decided to reduce the rest interval of workers from 40 minutes to 15 minutes. However, due to heavy workload and reduction in time of rest interval, efficiency of workers went down and it led to a fall in production level, instead of rising.
Which technique of scientific management should be followed by Gupta Bros?

Fatigue Study

Fatigue study refers to determining the amount and frequency of rest intervals required in completing a task. For example, normally in a plant, work takes place in three shifts of eight hours each. Even in a single shift a worker has to be given some rest interval to take her/his lunch etc. If the work involves heavy manual labour then small pauses have to be frequently given to the worker so that she/he can recharge her/his energy level for optimum contribution. There can be many causes for fatigue like long working hours, doing unsuitable work, having uncordial relations with the boss or bad working conditions etc. Such hindrances in good performance should be removed.
