What does vertical extension of a job typically involve?

Vertical extension of a job primarily involves job enrichment, which is focused on adding more depth, responsibility, and autonomy to a worker's position. This approach enhances job satisfaction and motivates employees by providing them with the chance to take on more challenging tasks and make decisions that influence their work outcomes.

In the context of vertical extension, job enrichment allows employees to feel more engaged and connected to their role, as they are given the opportunity to take initiative and contribute to their team's success in a more significant way. By contrast, job enlargement expands the scope of a job horizontally, adding more tasks of a similar level rather than increasing the responsibility or decision-making power.

Job rotation involves moving employees between different tasks or roles to promote skill development and variety, rather than increasing the depth of their existing job. Job scarification, while not a common term in this context, does not pertain to the expansion or enhancement of job roles as it may imply a different approach.

Thus, vertical extension of a job is best characterized by job enrichment, as it leads to increased motivation and satisfaction through the addition of meaningful responsibilities.
