You're welcome.
Of course you don't need someone sitting in IT watching your every move. But having logging in place does not mean that someone is doing just that. Most people couldn't care less what you're looking at, they have printers to fix.
IT departments are there to support the needs of everyone in the company. If HR / a Director wants logs of what someone has been looking at (none of IT's business _why_ they want it) then so be it. This is legal, its the companys equipment. No doubt this was also in the IT usage policy / employment contract you've signed.
The bottom line is. If you're worried about getting caught wasting time / doing something you shouldnt be doing on the internet, then you shouldnt do it.
