A new report has found almost 10% of teachers were the victims of online bullying by pupils.
DCU's National Anti-Bullying Research and Resource Centre has recommended a greater level of support for teachers' well-being and online safety.
The report found almost 15% of teachers were also aware of a colleague experiencing cyberbullying in the last 12 months.
Teachers cited increased stress, with many reporting that it 'significantly impacted' them during their working day.
The research also found that less than half had received anti-bullying training.
The research surveyed 577 post-primary school teachers on the issue of cyberbullying.
It found that cyberbullying was mainly perpetrated by pupils (59%) with most of this victimisation taking place on social media.
