This study attempts to explore specific school teachers’stress when they communicate with
parents through mobile phones. Mobile communication is very convenient and efficient and
sometimes it brings good educational effect. However, the number of teachers who are
stressed by mobile communication with parents is increasing. As stress and subsequent
exhaustion of teachers have negative effects on the quality of public education, it is
necessary to examine the relevant job stress among school teachers. For the study is
adopted a qualitative case study method that could be an effective research device making it
possible to get closer to the reality of this phenomena, that is, the teachers’job stress in
teacher-parent communication. The key task of the research is to understand how
communication with parents through mobile cause stress in school teachers and how they
respond to that kind of stress. The information and data obtained through 1:1 in-depth
interviews with 8 participants were sorted out and analysed. As a result, teachers
experienced stress when they contacted the parents with inappropriate information such as
late night, holiday, or during the class, and they requested only the convenience of their
own children. In addition, through social medias linked with the mobile phone number,
when the parent interferes with the privacy of the teacher or makes a friend request, the
teacher's personal mobile phone number must be informed by the request of the school or
limitation of the telephone facility. Experience. Teachers who experience these kind of
stresses tend to block parents from the list of specific social media friends list(such as
Kakao talk). Some teachers give up using social medias altogether and leave the account.
Some of them make extra phone or more phone number for parental support only, and the
like. The development trend of information and communication technology and the aspect of
teacher-parent relationship, it is expected that the teachers’ stress related to this might
increase in the future. The government need to support for the protection of teachers’
privacy and personal information, access to teachers' rights to education, improvement of
school telephone facilities, or payment of business mobile phone for teacher-parent
communication.
