I’ve logged into FR from every job I’ve had. Guess it really depends on the work place. How much do you think they pay attention? I’ve been in small companies where they don’t pay attention cause we’re all friends. And I’m currently in a big company where they don’t care cause there’s 10,000 of us scattered all over the world. Also my desktop isn’t on the corporate domain but in a test environment, so I do gain a little extra anonymity. I’ve got friends at work who VPN into their home desktop and do “questionable” (by corporate standards) things from there. I think that’s part of why they dropped the ESPN block, somewhere along the lines they figured out that when you hire smart people they’re gonna do what they want and you can’t actually stop them.
Someone I know who worked for Motorola said a guy there got canned for logging into some “adult” site with his work computer from home (so he was on his own network away from their filters). But when he plugged back in to the company network the system detected the cookies.
