Ask Slashdot: IT Personnel As Ostriches?

MonOptIt writes: I'm a new IT professional, having recently switched from a different sci/tech field. My first gig is with a mid-size (50ish) nonprofit which includes a wide variety of departments and functions. I'm the sole on-site IT support, which means that I'm working with every employee/department regularly both at HQ and off-site locations. My questions for the seasoned pros are: Do you find yourself deliberately ignoring office politics, overheard conversations, open documents or emails, etc as you go about your work? If not, how do you preserve the impartiality/neutrality which seems (to my novice mind) necessary to be effective in this position? In either case: how do you deal with the possibility of accidentally learning something you're not supposed to know? E.g. troubleshooting a user's email program when they've left sensitive/eyes-only emails open on their workstation. Are there protections or policies that are standard, or is this a legal and professional gray-area?
