The purpose of this research is to analyze the challenges and responses of elementary teachers, as classroom managers in this rapidly changing era. For this purpose, in-depth interviews were conducted for nine incumbent teachers from various perspectives, including their own experience perspective and their fellow teachers perspective. As a result, the challenges and responses facing teachers from the perspective of the self-experiences were 1) The educational scene of topsy-turvydom: defense priorities for survival, 2) requests treated as VIP who want to be respected rather than regular parents, 3) demands for teachers’ unlimited responsibility and parents who want to enjoy extreme convenience. Challenges from a fellow teacher’s perspective are 1) between drawing lots(parents) and turning bombs, 2) teachers who are faithful to inertia vs holding time bombs in the classroom 3) female teachers who are difficult to be free from raising their children. To support these challenging teachers, several alternatives are needed for them: 1) enhancing the teacher training system and on-site suitability, 2) preparing a preliminary first-grade parental adjustment program under the auspices of the Education Support Agency, and finally, 3) one-stop service counseling system to ensure thorough anonymity.
