Leadership is a specific process, which includes giving purpose, direction and motivation. In its core, it is a positive process. However, the phenomenon of destructive leadership, which is quite opposite from „true“ leadership, is getting more and more common. Giving a purpose is often replaced with coercion and giving direction and motivation with insults and punishment. Consequences of the aforementioned are extensive and may be hazardous for the entire organization. The worst part is, that the individual who is under the effect of destructive leadership, especially destructive leadership that goes unpunished, has a growing chance to become a destructive leader himself. This phenomenon is particularly dangerous among the cadet population and others who are being trained for military officers. The purpose of this final assingment, „Personality and destructive leadership“, is to give insight in the way in which personality and destructive leadership corelate, with fundamental idea that in that way destructive leaders can be detected. Assingment gives a review of theories of leadership and a review of personality with the purpose of pointing out causes of leaders' destructive behaviour. Furthermore, it defines destructive leadership in detail, and gives directions for practical application.
