SECONDARY SCHOOLS are at “breaking point” thanks to the Tories slashing 15,000 staff, headteachers warned today.

New research shows that English secondary schools have lost an average of two classroom teachers, two teaching assistants and two additional support staff since 2015.

The education unions behind the research, which is based solely on official government statistics, said the reduction in the workforce stemmed from real-terms budget cuts of £2.8 billion in that period.
