If you want to be more effective as an employee you need to take on the responsibility of setting priorities. And you don't do this before you have a certain level of skill and understanding, but once you do you become _much_ more effective if you know how to work towards goals instead of just being told what to do. And it's not that you contradict your boss' priorities. It's that you do what needs doing: those priorities feed into it, but also the reasons for those priorities.
