The key job of a manager is to say no. It is not to optimize the work distribution but to control the scope of the work that is done. A critical distinction between manager and leader is the former has more focus managing shape of the playing field and the rules while the latter is more concerned about pushing towards results. Last but not least management is about gaining, using and maintaining power. Without it saying no is not possible.
