Because a school can only function normally with a certain number of teaching personnel, if there are too few students, there will also be too few staffers, and the teachers will have to take on administrative responsibilities like payroll, planning lunches, and so on, as well as attend training sessions and go away on business.
因為學校有固定的教職員人數，運作才會正常；若學生少，老師一定也少，他們就得兼任行政工作，如掌管薪水清冊、營養午餐等，又要參加研習、出差，一旦外出就要調課，擾亂教學進度。
