At our school we currently have 3 science tech's (2 part-time and 1 full time) to support the science dept & science teachers. We the IT dept have myself (IT Network Manager) and 1 senior IT Tech for the whole school, we look after over 500 clients pc's/laptops, 13 servers, wireless, telephone system, the IP CCTV, the technical side of the VLE, etc - kinda sounds like a joke. It seems like us that work in IT are "second class citizens", if you're not directly linked to an academic dept it's "try again next year". If you're linked to an academic dept, well you get the idea...
