text: Think about this realistic occurrence of a student getting hurt or getting sick is a big concern for the principal because they would definitely need a janitor specifically for after school hours. In result the principal would have to have every students medical information and parents contacts incase of an emergency like the one mentioned above. Because these activities would most likely be after school but some during school hours to. These are the really important risks of being in charge of the whole school because if something bad happens you get blamed for it.
