Diplomarbeit aus dem Jahr 2007 im Fachbereich BWL - Personal und Organisation, Note: 1,5, Universität Konstanz, 93 Quellen im Literaturverzeichnis, Sprache: Deutsch, Abstract: The aim of this diploma thesis was the construction of a scale suitable for measuring the ethical leadership behaviour of executives towards their members of staff (EF ) as well as the subsequent evaluation of the EF and the investigation into its effect on the staff behaviour in German leadership practice. As there is no scale for measuring the EF in the topical research as yet an operationalisation of the construct EF and the development of an EF scale was conducted on the basis of the existing literature. A total of 234 German leading executives participated in the written questioning, which was carried out with the help of a mailed questionnaire. In order to be able to check the effects of an EF on the staff behaviour the questionnaire contained two scales already checked and proven in research for the constructs Organisational Citizenship Behaviour (OCB) as well as Leader-Member-Exchange (LMX) beside the self-constructed scale. The results of the study point to a very pronounced EF of the German leading executives, with the younger leaders seeming to lead their members of staff less ethically compared to the older ones. Furthermore a significantly positive context between the EF of a leader and the OCB of their followers was noted.
