Too many teachers and pupils are in schools that are not adequately repaired and maintained, the TUC has heard.
NASUWT National Executive Member Russ Walters said teachers and pupils were in some cases being exposed to asbestos and children were learning in substandard classrooms.
He told a debate at the TUC Congress in Brighton on safety in school buildings that parents expected their children to be safe when they were sent to school. But this was not always the case, he said.
Mr Walters told delegates: “The NASUWT has been warning since the then Coalition Government scrapped the Building Schools for the Future programme in 2010, that too little money is being invested in maintaining and improving school buildings.
“And that lack of investment has been seen in responses from our own survey of teachers.
“A third of teachers who responded said their school building was not fit to teach in and 38% said their buildings were not good for pupils.
“What message is this sending to our pupils, that almost two fifths are schools are in conditions that teachers believe are not good enough?”
