Conclusions
Narcissism is linked to positive elements such as charisma, creativity and vision as well as negative results for an individual and its context (such as failure to develop and maintain long term relationships with other people, cases of unethical behavior, obstructing communication). At the organizational level, high level narcissism is an indication of toxic leadership, while it is also connected to the abuse of power, nonproductive culture and organizational collapse. Even it can be supported that there is also a bright side of narcissism or that narcissism may be useful in certain phases of organizational development, narcissistic behavior should be evaluated in relation to specific context and circumstances. In any case companies should be in a position to diagnose and eliminate problematic situations through appropriate mechanisms and policies (e.g. obligatory seminars for and discussions with highly ranked executives about self-awareness and the ability to diagnose personal weaknesses, utilization of employee evaluation data, careful fact and behavior based selection of executives for promotion, development of emergency succession plans) so that potential problems from narcissistic behaviors are prevented.
