TEACHERS at a Glasgow secondary school launched 12 days of strike action today as they accused bosses of failing to act against violent and abusive pupil behaviour.

NASUWT, which represents workers at Bannerman High School, slammed the Scottish city’s council for “failing to implement initial measures agreed with the union that would ensure staff safety and that pupils' needs are met appropriately to restore order.”

The charge follows allegations of students shoving and shouting at teachers, brandishing screwdrivers, damaging the building and engaging in theft of property.
