More than one third of teachers in the UK are victims of online abuse, with majority of them being women, says a new study.
The findings of a survey conducted by Plymouth University found that almost 72 percent of the abuse originated from students but over a quarter was initiated by parents.
It also suggested that while most of the slurs come via social network chats, there are also some Facebook groups that are specifically formed to abuse teachers.
In some instances, whereas some people posted videos of teachers in action on YouTube, some took to ratemyteacher.com to attack their teachers posting scornful comments.
When asked if they had been victims of online bullying, 35 percent of the teachers answered affirmatively of which 60 percent were women.
"This parental abuse is something we haven't come across before," the BBC quoted Prof. Andy Phippen, the author of the report, as saying.
"Sometimes they are abusing other children at the school as well. Schools need to clamp down on it, or it will increase in prevalence," he added.
