This study argues for a new theory in school management based on the notion of positive containment which benefited from the integration of the main two patterns of leadership, i.e., the democratic and the authoritarian. In this theory, the school principal has to deal with one external and five internal circles of positive containments. The principal has to deal with his school staff in an open friendly democratic spirit. However, he has to practice the role of the good tyrant who depends on implicit bargaining with his school staff. In other words, When they perform his orders as stated, they will be rewarded. However, when they do not follow the orders, they will be held accountable. The study concludes with several expected outcomes as a result of theory implementation, including: the theory supports the principle of human relations in school work and works on involving everyone in school tasks no matter how small their job titles are.
