The first point of your comment I completely disagree with; the second point acknowledges why the the first point is bullshit to begin with. Yes, someone can be incompetent and require corrective action. This was not it and completely, grossly unacceptable. That he had to adjust his behavior is an acknowledgement to this. We are all flawed humans; but some are more flawed than others. That being said, if it’s true he has reflected and taken corrective action on his own negative behaviors, kudos to him.
