Quarter of teachers are attacked by pupils every week
Teachers are being regularly attacked by pupils, with almost a quarter saying they suffer physical violence at least once a week.
In a survey of 4,912 teachers, 89% had suffered physical or verbal abuse in the last year.
About 24% said pupils were physically attacking them at least once a week, and 4% said this happened every day.
The poll by teaching union the NASUWT, ahead of its annual conference in Belfast this weekend, also found 86% of teachers have been sworn at, and 42% verbally threatened.
Almost three in 10 (29%) have been hit, punched or kicked, and 39% have been shoved or barged.
Others have been spat at (7%), headbutted (3%), or had personal property damaged (27%).
One teacher, who has since left the profession, said: "Having taught for almost 40 years I have witnessed a demonstrable and seemingly unstoppable deterioration in pupil behaviour."
Four in five of the respondents (81%) said the abuse had affected their enthusiasm for their job.
Only 15% felt pupils were dealt with appropriately when incidents were reported.
Chris Keates, NASUWT general secretary, said: "Pupil indiscipline is now second only to workload in teachers' concern about their job and is a contributory factor to the teacher recruitment and retention crisis." The Department for Education said: "We are committed to tackling bad behaviour in schools have made great strides in empowering teachers to tackle this issue and have recently announced a £10m investment to support schools to share best practice in behaviour management."
