Problems in communication with manager has begun after I have done remarks about low team spirit, huge turnover (as in managerial team as in developers team). In my work I had difficulties with handover, clearly defined tasks and support from the manager. Aggressive and blaming environment, not so comfortable to stay work. My decision to change the project was a reason to receive from manager the worst feedback in my whole life. Artificial creation of obstacles with a change of the project through release to reserve. One manager's feedback can cross out all other positive feedbacks.
