> ...the most effective solution is very simple... No, definitely not simple. These people have intrinsic deep-seated personality defects. Sure, personality changes do occur in life but they take A LONG TIME, and barring trauma, aren't precipitated by any single event, especially something as as simple as people creating humiliation in a workplace. In other words, you can't "change" an assh*le or force them to curb their personality to the point where it's not noticeable. You either grow a thick skin, avoid them, force them out, or what most orgs do, nothing-- just wait for their behavior/value ratio to cross a line that precipitates expulsion from the group.
