A teacher friend of mine tells me she is regularly abused anonymously by pupils on line, and by some parents - who feel that their children are being treated unfairly.
Her classroom authority is constantly undermined and unpopular decisions criticised. The practice is particularly upsetting in her small community, where everyone knows each other.
Sadly the criticism and abuse are not limited to school activities - and often include personal insults about her private/personal life, usually just made up.
Consequently, this excellent and natural teacher is considering a career move (out of the goldfish bowl) into office work -
which doesn't attract the same perverse levels of attention.
