In corporate culture, the IT staff can be your best resource or your biggest enemy. They deal with idiots all day so say hello and treat them nicely. Not only when you have a problem. Bring them some donuts or something randomly. They don’t forget and will take care of you next time you have a computer crisis. I’ve gotten new monitors, extra keyboards for home, cords, whatever I needed because I took some time to say hi and ask how their day was going.
Same with the maintenance/facilities team.
They are two teams you want on your side.
