Dependable leaders are always on time, never make excuses, and stay on the job until it's done, regardless of obstacles. They often make personal sacrifices. During decision making, they state their ideas clearly and tactfully if they disagree with others above them. But once a decision is made, they put their disagreement aside and work to complete whatever assignment they receive.
