Answer:
Responsibilities.
Explanation:
An employee can be defined as an individual who is employed to work in an organization and as such is saddled with the responsibility of effectively and efficiently completing the day-to-day tasks that are assigned to him or her, for a specific period of time.
Hence, the long-term, day-to-day tasks that are assigned at work are called job responsibilities.
Additionally, job specialization can be defined as a strategic process which typically involves the ability of employees working in an organization to develop specific skills, knowledge, great expertise or professionalism and experience to perform their duties, tasks or job functions effectively and efficiently.
In order to gain the requisite skills, expertise and knowledge for job specialization, it is very important for the employees to have undergone an extensive training and a good number of years in work experience.
The main advantage of job specialization to a business firm or company, is to increase efficiency and productivity because the employees are able to specialize in the use of specific tools (equipments) to accomplish their tasks, as well as limit the level of error or mistakes in the production process.
