I know exactly who you guys are talking about. That manager has nine lives. Each time he blunders Astellas seems to just keep looking the other way. They really shouldn't though as once again they're going to lose good people who just can't stand to take it anymore. He is the definition of an emotional abuser, carrying out verbal aggression, dominant behavior, tearing down people's self esteem, shredding their self worth, making them feel like everything is their fault, public humiliation, playing the reps against each other, denying things he said previously when he's caught up in his own mistakes, etc... He can't see any of this though, classic narcissist. Most likely thinks his team adores him.
But at the same time he's the constant critic, the guy who will get you behind closed doors for plausible deniability so that it will always be a "he said/she said" situation. He crawls into their minds and corrupts their psyche so they feel incompetent. His victims will rarely be believed since he's the manager. Then, in turn the misuse of the performance appraisal system will come into play. Always does. I guarantee you will start seeing his team have compliance issues and other nonsense put on their coaching reports. I would put money on that.
Astellas constantly preaches the word "culture, culture, culture...," but sadly for reps with managers like this, the only culture they know is fear and the sense of betrayal when they speak up, but are ignored by HR. Shame on you Astellas.
