The reason why there must be a teacher on duty during school holidays: Because if the school has any urgent documents or things to deal with, then maybe the doorman or security guard doesn't have such authority or doesn't know how to do it.

Of course, if you encounter other emergencies, if no one can handle and find them in time, it may also bring unexpected consequences. Moreover, security guards and doormen may be sick or have a rest, which also requires teachers to be on duty.

Moreover, foreigners will come to school during the winter and summer vacations. For better reception, it is inevitable that the teacher is on duty. However, I hope that the school will consider the teacher, and from the teacher's point of view, let the teacher have a good rest during the holidays and arrange less tedious work.

In today's environment, due to various reasons, the development and prospects of various industries are very depressed. The most advantageous positions now are stable jobs such as teachers and civil servants. This is why college students are so keen on these two jobs.

But enthusiasm means that the competition will become very fierce, and the chances of successful admission and landing will become smaller and smaller. Therefore, for college students now, whether they are normal students or students of other majors, they need constant efforts to enter the post of teacher.

On the one hand, we should constantly improve our academic qualifications, on the other hand, we should improve our self-ability and self-worth, both of which are indispensable. Of course, college students who have received higher education have plans and plans for the current situation and the way to go next.
