The research sample consisted of (200) male and female teachers distributed in (10) schools for males and females. The study concluded the following results: There is a correlation between occupational stress and the total dimensions of burnout at the level of (0.01). The study also found that there is no statistically significant relationship between occupational stress and job performance. Also, there is no statistically significant relationship between burnout in its four dimensions and the job performance of the teacher. It also became clear through the study that there is no statistically significant relationship between the physical dimensions of combustion and the job performance.

Despite that, there is a difference between the two averages, which suggests that there are differences in males that they are less burning than females.
