Shift work is the arrangement of  work schedules so that some employees are present at  the work premises all 24 hours of the day . Though the shift timings and hours vary from country to country depending on the local labor laws, in most organizations, 24 hours is usually divided into three shifts of 8 hours each. There may be some overlap between 2 shifts as the supervisor from one shift hands over charge to the supervisor for the next shift to ensure smooth operation.

Many companies have an office and factory in the same premises, and the timings of  the day shift often coincide with the office timings for these companies, so that resources are utilized efficiently. In service industries, the number of  shifts in a day is usually constant through out the year,  but for manufacturing industries, the  number of shifts depends on order booking position.

When there are lot of orders to be completed and production is to be maximized, the factory may operate in multiple shifts. Soon after the end of  the financial year,  production is less and only a single shift is sufficient .
