"Online abuse directed at teachers by parents has doubled in the last year due to an increase in the use of social media platforms like Snapchat and Instagram.
In the last year, 40 per cent of teachers said they had been the victims of cyber bullying by parents, compared to 21 per cent a year earlier, a new survey has found.
Threats made by parents also rose by 8 per cent from 2014.
The increase coincides with the growing popularity of social media platforms like Instagram and Snapchat, with abuse on both rising 5 per cent from a year earlier.
Most remarks are either abusive, sexist, racist or homophobic and are made in relation to a teacher's looks, competence or sexual orientation."
