I work at school, and am part of the supporting personnel (I am not a teacher, nor a part of the management personnel). I do administrative work, copying, sometimes I do computer work. I clean used cups, knives, spoons, etc. and I clean the kitchen of the break room (where the personnel are during breaks). I care about internal and incoming and outgoing external physical mail.
Soon I will make a move to computer technology and at this time my boss and I are making preparations to enable that move.
