Behavioural Approaches to Leadership concerns leadership styles, such as, autocratic vs democratic, and people-oriented vs task-oriented (Michigan studies). Mary is the headmistress of a small private school with 800 students. She manages the school that employs 40 teachers and other non-teaching workers and must make many major decisions affecting the school. She was a highly respected senior teacher in that school and was only recently promoted to headmistress. Many of the teachers are very professional, independent, and competent in their teaching. However, Mary would like them to contribute more to the overall operation of the school, apart from just teaching. Explain with justification the leadership styles most suitable for Mary to adopt when managing the 40 teachers.
