Job Enlargement: It means expanding the number of tasks, or duties assigned to a given job. Job enlargement is naturally opposite to work simplification. Adding more tasks or duties to a job does not mean that new skills and abilities are needed. There is only horizontal expansion. It is with same skills taking additional responsibilities like extending working hours etc. Job enlargement may involve breaking up of the existing work system and redesigning a new work system. For this employees also need to be trained to adjust to the new system. Job enlargement is said to contribute to employee motivation but the claim is not validated in practice.
