Understanding Work Hours in Different Industries
09 hours in a day means 08 hours for working, and the rest are for rest/lunch or tea breaks, where production stops, and workers/employees leave their workplace to go for a proper lunch. In that case, we have to exclude the lunch hours from the duty hours. This means the total duty hours will be 08:30 or 09:00 hours, depending on the lunchtime.
In most companies, the general shift timing is from 09:00 to 05:30 or 09:00 to 06:00, where the lunch timing is for 30 minutes, then duty will end at 05:30. If the lunchtime is for 1 hour, then duty will end at 06:00 pm. This shift mostly covers commercial staff such as HR, Account, etc., and this type of industry is called a non-continuous process.
Continuous Process Industries
In a continuous process where machines cannot stop due to the process, the shift is mostly for 08 hours, like 06:00 to 02:00, 02:00 to 10:00, and 10:00 to 06:00. There is a general shift of the last mentioned.
