What is a job role?

scope of job role means doing the job you are assigned to do and only that job role. for example if a business teacher went and taught a geography lesson, they would not be able to attempt it because they only have a superior knowledge of business and only that subject. in a business scope of job role would be a manager who works in the back office of a business not knowing how to communicate face to face with the customers because that is not what they regularly do.
