Cyberbullying of teachers by their pupils has not been researched as widely as adolescent bullying or cyberbullying. The cyberbullying of teachers by pupils has been defined as “the creation of digital texts, images and recordings that portray the teacher in ways that are demeaning and/or ridicule the teacher, which are then transmitted electronically to others" (Kyriacou & Zuin, 2015, p.267). This research attempts to provide a diverse understanding of the online lives of teachers in post-primary schools in Ireland. Some of the variables for examination include how teachers self-regulate their profiles on social media, the security and privacy prevention tools used and their attitudes towards communicating with students online. This research investigates the types of cyberbullying that teachers experience and how this influences them in their roles as teachers within their school environment. Negative physical and mental health effects including severe stress, fear for personal safety, teacher and pupil performance has been identified as a result of pupils bullying and cyberbullying teachers, this is an additional area of examination. This research utilises a quantitative approach to provide further insight into teacher cyber victimisation to develop support structures for teachers and schools.
