I do surf the internet very frequently while on the time-clock, however:
At the place where I work (a ski resort), the guys in the Resort Business Systems Department have one of many ways to literally watch every single keystroke and mouse movement on all of the company's computers. Each computer at the ski resort has a unique barcode and number, and all those guys have to do is to simply enter in that number on their computers in the RBS office and then PRESTO! they're able to check out exactly what I (or anybody else who works there) am doing on that computer at that exact moment. With this in mind, I never look up any kind of tickling sites (or any other adult sites, for that matter) while I'm at work. It's a pretty decent job, so it's really not worth getting fired over something like that.
Does this help to answer your question?
