When I see something that needs fixing, I let the Sub office know. Like , a few weeks ago I told them the water fountain on the other side of the school is broken. (I don't know if they will fix it or not) I also let them know about the broken faucet in the restroom. And the class with the broken announcement system. Recently, I did a class with a broken window in the class, not a cracked window, a broken one with a hand sized hole in it. (I am glad I brought my coat) I let the Sub office know and they will tell my friend the maintenance man to fix it. I hope that I am not steeping on any Teachers toes, so to speak. I do have common sense and a huge hand sized hole in a classroom window will make for a lot of A/C and (This time of year) Heater running and trying to cool and heat the whole planet - due to the big hole in the window. Looks, like ether a sheet of glass or some tape with a makeshift patch would be better.
