The National Union of Teachers (NUT) vowed to step up its campaign of industrial action at its annual conference in Brighton. Delegates backed a priority motion which calls on the union to co-ordinate national strike action in the week beginning Monday, June 23, if significant progress is not made in resolving the long-running dispute. The NUT has said it would not rule out more than one day of strikes, and the resolution also left the door open for further action in the autumn. The move leaves schoolchildren across Cambridgeshire facing the prospect of school closures and disruption to lessons. The resolution was backed by a large majority but was not passed unanimously. The Department for Education has previously condemned the unions strike action, saying it disrupts families and holds back childrens education.
