One in five UK teachers have been cyberbullied by students and/or their parents, according to a survey published by the teachers union NASUWT. Most of the comments were posted by secondary pupils, and most relied on Facebook to deliver their toxins. Most teachers didnt report their pupils abuse to their employer or to police. The majority of those teachers who reported incidents to the police said no action was taken against pupils or parents, and 76% said parents were not taken against them.”]
