11)Non technical coworkers will assume that if it's related to IT, you are an expert.

If you're a programmer, expect them to ask you about networking, and vice-versa, if you're a developer, expect them to ask you about support, et cetera...

12) You have no freinds at work outside of IT. IF you're lucky enough to have an ally or two in 'the business' consider yourself lucky, you are a convenient scapegoat and non-IT folks won't hesitate to throw you to the wolves.

13) The business considers you to be a COST center, not a profit center. You need to be prepared to demonstrate your value or you'll be gone the moment there are layoffs.

14) Expect to be out of work, IT is an Ebb and flow industry, when times are good, everyone wants you, when times are bad, nobody wants you. Have at LEAST 6 months savings in the bank at all times.
