This paper reports a research study carried out on teacher burnout with a group of English instructors (N=44) in order to identify the major factor(s) leading instructors to burnout at various levels. A survey research model was first applied to find out the instructors (N=37) with a burnout problem and categorize them at different levels of teacher burnout. The next step of the research was an interview carried out with 12 instructors who were selected randomly from the four different levels of burnout. The results show that the instructors from the different levels unanimously believe that the major factor of their burnout is the administrative applications in their institution, which was coded as a micro variable. It was also revealed that the instructors with a high level of burnout displayed "Alienation to professional identity" behavior. (Contains 3 tables.)
