I'm the only "IT" guy, we have 5 others (1 manager/programmer, the others programmers) that are upgrading/developing internal applications. I take care of all the support issues (except for those internally developed apps). We've recently hired a sort of level-1 person, that is here part time.
Job demand is such that we can just barely jusify having the part-timer - as this person's position has to be "billed out" to the other departments. Myself, I'm not billable for most of them. Strange, I know.
Overall, we have around 200 users, according to active director. We have around 20 servers. Computers, we have around 300 or so. Why, you might ask? We have computer labs that the public can use...that we have to maintain.
By myself, I get more and mroe behind, projects get delayed, ideas are never fleshed out. With the part-timer, I get enough breathing room that I can do more, even though I have to walk this more technical person through things...at least they get it, where our users don't.
