Actually it's a nifty product that I'd never use.
If I'm ******** off and my boss comes by and says, "Hey Tom, what are you doing?" the answer he'll get will be: "Nothing, really. I'm just ******** off for a few minutes. You need me to do something?"
When I'm working, I work hard. When I'm ******** off, I'm not pretending to work. I'd rather tell someone I'm ******** off than try to cover it by lying.
What's the worst they can possibly do?
Yell at me? Good luck with that.
Fire me? I'm ok with that. I'd take my ball and go home. I can always find another game without much hassle at all.
If I ever screwed up I probably wouldn't have all that leeway, but if I ever screwed up I wouldn't deserve it either.
Still a neat gadget.
