The purpose of this study is to investigate high school English teachers' perceptions about their teaching job. The study focused on four areas; instruction, relationship with students and parents, working environment, and teaching profession. For this study, 126 English teachers from 15 different middle schools in Kyungnam province participated, and a questionnaire was used for the investigation. The findings revealed that the teachers perceived positively the effect of English class on students' English learning, and their dedication and confidence to English teaching was high. However, the teachers responded that they mainly used grammar translation method in class and viewed the lack of time for preparing their class and various limitations using learner-centered activities as the most significant problem. Also, the teachers responded that they had hard time in class because of students' demotivation and students' different English proficiency. Teachers in this study felt stressed due to the teaching load and excessive nonessential workload. It should be noted that among 126 English teachers, only 26 English teachers answered that they would be a high school English teacher if they could choose a teaching job again. In order to adequately support hight school English teachers, the factors influencing teachers' perceptions should be explored in relation to the teaching career and the size of the school.
