Which aspect does job enlargement focus on?

Job enlargement primarily focuses on increasing the variety of tasks that an employee is responsible for within their role. By adding more tasks, the employee encounters different activities and responsibilities, which can enhance their engagement and reduce monotony in their job.

This approach can lead to greater job satisfaction as workers feel that their roles are more comprehensive and less repetitive. Instead of just performing a single function, employees are encouraged to take on additional tasks or responsibilities that are at a similar level of complexity, leading to a more enriching work experience. This strategy can also help develop a wider range of skills in employees, contributing to their overall professional growth.

The other options, while important aspects of workplace dynamics, do not align with the primary focus of job enlargement. Enhancements in authority and increasing pay relate more to job enrichment or motivational factors rather than task variety. Job security pertains to the stability of employment, which is a separate consideration from the tasks assigned within a role.
