I can't believe people are still publicly posting stuff about their bosses. Surely there has been enough press coverage about people getting fired for fb/twitter antics
Au contraire, regardless of whether or not it's wise to diss your boss online, the last thing we need more of is mass knee-jerk reactions to information over-reported by the press.
Well according to the Gervais principle, there are two likely possibilities here. If it's a Loser insulting his Clueless boss then he probably has little to lose and probably enjoys the risk of his boss finding out while sharing a good laugh with his friends. On the other hand if it's a Clueless insulting his Sociopath boss then, well, there's probably a good indicator of why he's stuck in the Clueless caste.
I think this is so naive. Sure a "good" boss probably won't be snooping on his or her employees. However, I'm pretty sure most bosses are humans and humans tend to snoop on each other
