In the shift schedule, T stands for normal class, O stands for personal leave, K stands for absenteeism, and P stands for training break.

Scheduling means that everyone who goes to work knows his working date and procedure, because everyone has a holiday.

You can let employees go to work according to the procedures on the schedule, come without saying anything, or don't come without saying anything. It is often said that Fiona Fang cannot live without rules, so with the shift system, everyone will go to work according to the rules.
