When a worker has to learn only a specific, highly specialized task, that individual should be able to learn to do it very efficiently. However, this efficiency could eventually become inhibited by job monotony and boredom. This situation could be alleviated through

Job Rotation

Explanation:

Job Rotation is a management strategy in which workers are transferred or shifted at frequent intervals among two or more tasks or positions to expose them to all of an organization's lines of business.

This is a pre-planned strategy with an aim of checking the abilities and capabilities of the worker to position him or her in the right position.

It also decreases the job's tedium and provides them a broader knowledge and enables them achieve more understanding and perspective.
