Answer:
Leisure time is time spent engaged in an activity for my own personal enjoyment or growth. Idle time, on the other hand, is time spent on whatever activity happens to be at hand.
Idle time is paid time that an employee, or machine, is unproductive due to factors that can either be controlled or uncontrolled by management. Idle time can be classified either as normal or abnormal. Minimizing idle time is key if a business wants to maximize efficiency over long periods of time.
