When we talk to people about leadership in organisations, they generally define it as being about getting results (or objectives, etc) out of people. They define leadership this way for two good reasons: because they themselves are in fact no longer leaders (there are people in other departments in their organisation who do that work), and because they get rewarded on the basis of the results that their people produce.
This suggests the ends of leadership are the results, and the means are the people. It suggests leaders should use people to get what they want, treating them as human resources and not human beings.
In this video Sean Hagger introduces the radically different Legitimate Leadership approach to leadership in organisations.
