In IT, the new CTO brings his colleagues who all got laid off from his ex-workplace due to M&A. Almost all the management positions till the Director levels are replaced with the members of his old boy's club.

They are all behaving in the same fashion that their only purpose in AutoNation is to please their club leader and has zero concern on the well being of their team.
