Cyberbullying was among the topics debated at the annual convention of the Association of Secondary Teachers Ireland (ASTI) this week, amid a call for stronger legislation to deal with online harassment.
A recent survey carried out by Red C, on behalf of the ASTI, showed that almost one-in-five secondary teachers have experienced some form of work-related cyberbullying. The most common forms of abuse involved receiving angry, rude and vulgar messages, as well as videos of teachers uploaded without their consent.
