Job specialization is the focus and refinement of a certain area of expertise at work. On the one hand, job specialization can make workers less flexible to perform other types of jobs, but it reduces training time, as workers focus on a certain set of operations and actions during work. It also increases leisure time, because after mastered skills for a particular specialized type of work, they do not have the need to learn some other skills and work operations. They can spend that leisure time on personal education or enjoying art, etc.
