everybody already figured that out. I read your previous posts. When you asked for direct reports, your boss knew your intention is not to get the job done but to build your own team to increase your "influence". When you suggest making changes to process or clearly define your JD, people know your true intention is to define "who direct who", "who talk to who", the fact that you do not feel secured made you hungry for power, over calculated in dealing with colleagues, unfortunately, you did not hide your agenda that well, everybody figured that out. Nobody likes a over ambitious, over calculated and abrasive co-worker in their team, that is way people in your team did not even give you a warm goodbye lunch.
Sorry, I may too harsh on you but that how I feel.
