The research aims at gaining knowledge about interpersonal competencies at work when professionals lead and counsel the change processes of other individuals in accordance with the norms and values of the profession. Norms and values are disclosed from the ethical guidelines for five professions (physicians, nurses, social workers, psychologists and teachers). Critical incidents in the five professions are analysed to obtain knowledge about norms and values in a working relationship between the professional and the other individual. The personal competencies that meet the requirements of the ethical guidelines are discussed. The examination of norms and values concludes with three primary categories to denote ways of performing: Recognition, treatment and exercising authority. The analysis of critical incidents shows similarities in value working relationships across professions in aspects of time, personal qualities, relations, autonomy and motivation. Competencies, in accordance with ethical guidelines, are disclosed when the professional's respect for the other individual's dignity interacts with the other's trust in the professional's authority. The interaction establishes a context for the other’s change process. The context is maintained in the way the professional pays attention to the other individual's flow of experience. The maintenance depends on the professional's awareness of the other in his/her communication and judgment. The research brought forth knowledge of what makes up the competencies and their interactions. The knowledge contributes to education where professionals lead and counsel the other's change process.
