The guiding values of the members of the Y-generation are shaped by their biography and are expressed in their striving for openness, independence, individuality, maximisation of meaning, performance and personal development. In this way they correspond to the changes in the world of work and sales and reflect society. This makes them independent and sometimes disoriented. In management relationships they thus elude control. The challenges for managers arise from the contradictions of this generation with a high willingness to change and the change in leadership roles. As a result, new paradigms in the leadership of millennials are needed. Communication needs to be informal, personal and emotional. The focus here is on the individuality of the individual as a worker and human being. The leadership of Millennials is one.
