Teachers’ job satisfaction is a crucial factor to determine the quality of education in that it affects their dedication and participation. While teachers’ job satisfaction in general has been widely investigated, subject-related job satisfaction has been sparsely explored. Thus, this study investiaged both general and subject-related job satisfaction and compared them. A total of 117 secondary English teachers in Seoul participated in a survey which measures job satisfaction in terms of seven factors: relationship with people, job duties, work environments, opportunities for professional development, compensations, administration systems, and recognitions. Overall, the participants showed a modest level of satisfaction in both general and subjet-related jobs. Yet, subject-related job satisfaction was higher than general job satisfaction. They were particularly satisfied with their relationship with students and teachers. They also showed high satisfaction with recognition they receive as a teacher as well as an English teacher. In contrast, they were dissatisfied with compensations and workloads in general, and the number of students in charge and administrative support in teaching English. Finally, their job satisfaction was affected by gender, school type, position, and marriage. Based on the results, suggestions to enhance secondary English teachers’ job satisfaction were made.
