If managerial leadership means deciding responsibly in a complex situation, the ethical dimension of leadership — besides its analytical and instrumental aspects — has to be clarified. I present and discuss several essential aspects of managerial ethical leadership: (a) some major presuppositions (the concepts of leadership and responsibility), (b) three normative-ethical tasks of the activity of leadership (perceiving, interpreting and creating reality — being responsible for the effect of one's decisions on the human beings concerned — being responsible for the (...) implementation of corporate goals) and (c) some claims on the leader as a subject responsible for his or her own activities. I shall conclude by adding some reflections on the limits of managerial ethical leadership. (shrink)
