This research was to investigate teachers’ emotional rules toward different people when working at Private Secondary School in Malaysia. In order to reach our research purpose, we used qualitative research as method, four teachers working in Confucian Private Secondary School as our subjects. Through interviews, we collected and analyzed our results. In this research, we found that there were front stage behavior and back stage behavior when teachers encountered students, co-workers, superiors and parents. The emotional rules of front stage such as self-adjustment when faced students’ achievement or behavior. Instead of being angry with them, teachers changed their mind, treated them sincerely and tried to understand the situations. As for being with co-workers, some of them gathered together encouraging and understanding each other; however, if encountered those who were hard to get along with, they would feel disgusted and troublesome. When negotiating with superiors, if problems came and teachers were helped, they would feel happy. Yet, if those superiors were rigid and passive, they would feel perplexed. Last but not least, when encountering arrogant parents, teachers constrained their emotions in order to handle things. Besides, back stage was a place for emotional catharsis. With a view to comforting and adjusting themselves, encouragements from partners, complaining together, mind-changing or traveling together were all the ways teachers vented emotions and released themselves.
