Reason to not to add your boss to Facebook

This is why we should check who ever we add to friend list before we approve the request...so that things like this can be avoided...but for me, i think the boss him/herself is not professional from his/her comment (if it's true la), u don't mix up ur emotion with ur work decision, furthermore if the employee give his/her comment after the working time, u don't have right to fire him/her just because of this typical reason...but in this comment i can see that the employee him/herself not so well performed, there the boss have a valid reason...hahaha, all in all, actually all boss out there, we as human can never satisfied everyone around us, no matter how good u are, so just accept the facts...hehe
