Transformational leadership is important because it provides not only direction but it also creates opportunities for professional development. This qualitative investigation explored how medical doctors, in order to be transformative, should negotiate with advanced practice nurses while working in collaboration with them. The results first suggest that medical doctors and advanced practice nurses should negotiate appropriate levels of supervision in their working relationship commensurate with the education and experience that the advanced practice nurses bring to the practice. Second, mentoring should be a reciprocal communication process between medical doctors and advanced practice nurses, where thoughtful feedback facilitates appropriate adjustments in respective communication and time management styles. Third, educating necessitates mutual learning, with each party acknowledging the possibility of learning from the other and being sensitive to the value of what the other contributes to the working relationship. The authors conclude that effective leadership involves negotiating along these dimensions, which will contribute to effective team-building.
