The concept of vertical job enlargement focuses on which of the following?

Vertical job enlargement is primarily concerned with enhancing responsibilities within a job role. This approach expands the breadth of a job by adding tasks but also adds more complexity and authority, allowing employees to take on more significant responsibilities. This can lead to increased job satisfaction as employees feel more valued and trusted, contributing to better engagement and motivation levels.

In many organizational settings, this enhancement aligns with increasing the level of decision-making power, providing workers with a greater sense of ownership over their tasks. It contrasts with horizontal job enlargement, which would focus more on adding similar level tasks without increasing the responsibility or authority tied to the position. By concentrating on enhancing responsibilities, vertical job enlargement plays a critical role in developing an individual's professional capabilities and career growth within the organization.
