Excuse me, is there any recruitment of logistics staff in public primary schools now?

Basically not. They are all looking for temporary workers, such as cleaning and security guards. As you said, the logistics services such as mimeograph room, equipment management personnel and computer room management are basically computer teachers and physical education teachers. There seems to be accounting and file management in the school logistics establishment. Those accountants used to be teachers, but later they changed. Even the person in charge of the library has to take a sociology test or something. Because our school used to be transferred from the factory and mine school, the original janitor was compiling it, but it seems that other schools don't have such a compilation. Those who attend classes at different times must be workers, not teachers.
