using fb at work could compromise your privacy. if you're working for a company where data security is very important, chances are the it department is like a big brother that has tabs on your every move while you're using your office pc. everything you do can be tracked and monitored. that includes how long you've been staying on a particular site, which sites you're visiting, and whatnot. that includes your 'i hate my job' and badmouthing the boss status messages.

i had a colleague in my old job back home who got a warning from our regional it simply because she uploaded a picture of herself with her office pc visible in the background on a social networking site. she used her home pc when she uploaded it but the it dept found it anyway. the warning said company/customer information may be compromised because some people might read what was on the computer monitor behind her. we were not allowed to take pics in the office after that.
