Staff at a secondary school are to strike over what unions called a "failure of management to act" to properly tackle "disruptive behaviour".
Union bosses announced teachers and support staff at Haydon Bridge High School in Northumberland would take two days of action - on 19 and 25 November - with members of the community invited to hear the teachers' concerns.
Headteacher David Nisbet said: "It is important that the education of the young people we serve is not disrupted by industrial action."
The National Education Union (NEU) and the NASUWT said they wanted to engage in meaningful discussions and that strike action was "always a last resort".
