Not everytime, but most of the time Manager's think they are very smart, because of which they become oversmart. Until a Manager does not co-operate with subordinates its very difficult for him be successfull, and it becomes difficult to continue. Same time subordinates every time are not wrong. I think most of the subordinates quit their job JUST BECAUSE OF HARSH MANNER OF MANAGER'S. I hope manager's understand that they are just incomplete if they r not cooperative or understanding with subordinates.
