More than a quarter of all incidents happened on a Monday, with Friday the day teachers are least likely to be abused, according to the study by the NASUWT.

Another pupil who stuck a middle finger up at a teacher was supported by their mother.
Of the recorded insults, almost three-quarters occurred in the classroom, with only a handful happening outside school.
Chris Keates, general secretary of the NASUWT, said: "There is a great deal of work still to be done to tackle the corrosive and debilitating effects on teachers of verbal abuse.
