A lot of studies have been done in the developed countries due to the importance of job satisfaction; however, only a limited number of studies have been conducted on English teachers' job satisfaction in Iran. Therefore, this study has been designed to recognize the amount of job satisfaction among Iranian EFL teachers regarding their gender, academic degree, and major. To do this end, both qualitative and quantitative research methods, a questionnaire, and a structured interview were utilized. To collect data, a validated questionnaire which was developed by Karavas (2010) administered to a sample of 53 males and females English teachers, teaching in different institutes, at private schools, and at universities in Genaveh Port, Bushehr Province. After gathering the questionnaires, all of the teachers were interviewed. The study findings provided the evidence that females were more satisfied than males. Moreover, the results indicated that the participants with BA/BSc significantly had higher job satisfaction than the participants with MA/MSc degree. But the comparison between the other groups did not reveal any significant difference. Furthermore, the findings clearly demonstrated that there is no significant difference between teachers' job satisfaction and their major. The results of the interview revealed that Iranian EFL teachers satisfied with their jobs because they like teaching, and the most important reason of all teachers' job dissatisfaction is their low salary.
