It appears this "IT guy (of whatever specialty) = general building superintendent" is quite a large and apparently growing phenomenon.
I feel your pain, it's the pressure of "we can get 10 guys in India for what we pay you" globalist, outsourced world agenda.
I'd say, with the utmost sympathy, (so no flames, plz) it's best to count your blessings.
But unlike most career IT folk, I do not work for one leviathan, rather I have numerous clients of varying size, most of them quite small, under 20 stations system wide doing various tasks.
In these shoes, I am not seen as "laying around idle" to be tapped to change light bulbs, etc. They perceive my presence as "he's here to fix the dang... (whatever)" but *whatever* is always right up my alley.
Seeing me as an expense ONLY related to the smooth operations of the IT infrastructure, they hesitate to ask me to linger on the clock to do extraneous mundane things.
That said, I am always actually offering to change out a few bad lights, take a look at the phones, etc., with the understanding this is by my good graces, not because they think they own my butt and think I'm idle and unproductive.
Face it, the climate has created the perception that ALL employees are liabilities, not an asset.
In fact back in my aviation days I flew a fellow into town for a business 'round table,' who had literally written the book a few decades ago on this fundamental shift in management "thinking." I was stunned by what this fellow told me, needless to say the world you see does not surprise me, I saw the plans being lain a long time ago.
I quote "thinking" above because it's really more "conditioning" so management is in line with this global agenda of "break the backs of the working class = moremoremore $$$ at the top."
If at all possible you should consider becoming a wild cat like I am, with a few smaller (and more appreciative, believe me) clients, rather than the "full time job" model.
That model is only going to get worse with time, until the people wake up and make fundamental political change... wait for it...
Google "Ron Paul 2008" for an eye on the needed change...
(insert gratuitous religious argument here

)
Anyway, when I voluntarily help with otherwise non-related electrical (even plumbing!) problems it is immensely appreciated, and a confirmation they have the right guy for the IT needs, rather than expected because I'm on any payroll.
It took a looong time to get here, but well worth it.
I remind you salaried types a lawn mover uses electricity, too...
