The number of teachers suffering from mental health problems due to the pressures of their profession has risen by over a third, a survey has revealed.
Some 38% of teachers told the Association of Teachers and Lecturers (ATL) there had been a rise in mental health problems among their colleagues over the last two years.
And over half (55%) of the 925 education staff quizzed said their job has had a negative effect on their mental health.
ATL general secretary Dr Mary Bousted said she was shocked at the results, but felt the data spoke for itself.
"Teachers, lecturers, support staff and heads are now so over-worked that it comes as no surprise that so many in the education profession suffer from stress, depression and other mental health issues," she said.

There are "no winners" in the teachers' strike with schools running as if it was "a snow day", head teacher Vic Goddard told Daybreak.

"I am sure I haven't pleased the union today by not having a partial closure. Heads have to make that decision - can I keep all children safe in my school?"
