What is defined as a collection of tasks assigned to an employee?

The choice identifying a collection of tasks assigned to an employee as a job is accurate because a job typically encapsulates all the responsibilities, duties, and tasks that an individual is expected to perform within an organization. This encompasses everything from daily activities to broader roles that contribute to organizational objectives.

In contrast, the other terms have specific meanings that differentiate them from the concept of a job. A role generally refers to the expected behavior and contribution of a person within that job or organizational setting, while a position is more specifically tied to an employee's rank or title in the hierarchy of the organization. A function could refer to the overall purpose or a specific duty performed within the job, but it does not encompass all tasks assigned to an employee. Therefore, defining the collection of tasks as a job is the most appropriate and comprehensive choice.
