The scientific literature indicates that manager behaviour may influence not only temporary psychological reactions in employees but also risks of more serious illness conditions such as depression and myocardial infarction. Destructive manager behaviours are quite common at our workplaces. When the manager is not ready to put in his/her personal energy in order to decrease bullying but rather remits the problems to formal structures constructive healing processes may be delayed. The vast majority of poorly functioning managers could probably change their attitudes and behaviours. How to influence them in the direction of aesthemetic engagement is a matter of educational principles. The programme Shibboleth offers an artistically based such educational principle which proved to be efficient in a controlled trial.
