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

>>Most bosses do not have the time, wherewithal or care enough to do this.

>>There is nothing wrong with people blowing of steam.

And each to their own, but it's easy to make a post private instead of public, and doing so seems much more prudent to me.
