Job Rotation implies systematic movement of employees form one job to the other. Job remains unchanged but employees performing them shift from one job to the other. This is described as job rotation.
With job rotation, an employee is given an opportunity to perform different jobs, which enriches his skills, experience and ability to perform different jobs. However, the jobs offered under job rotation are more or less of the same nature. As a result, he will be skilled to a new job which is more or less similar to his earlier job.
