The secondary school system will virtually grind to a halt in Kirklees today.

Tens of thousands of teenagers – as well as thousands of younger children – will have an extra day’s holiday as the one-day strike by teaching unions NUT and NASUWT has forced the vast majority of high schools to close their doors to students.

It is a mixed picture among primary schools, with some staying open, while others are either partially open or completely closed to pupils.

Among Kirklees secondary schools only The Mirfield Free Grammar and Sixth Form, Batley Grammar and BBG Academy are managing to stay fully open.

Nether Hall Learning Campus High School is only open to Years 12, 13 and 14, while Rawthorpe Juniors and Infants are all closed. But free school lunches will still be provided for all of their eligible pupils.

Newsome High School and Sports College is closed to students, except those in Year 11 sitting mock exams.

In Calderdale, Rastrick High will be open for Years 11, 12 and 13 and closed to all other students. Brighouse High, Crossley Heath and Brooksbank at Elland are all closed to pupils.

Teachers at some of the larger schools, such as Honley High, have mounted picket lines outside school. Others are travelling to a rally in Sheffield to hear their national leaders speak, while some are attending the West Yorkshire NUT rally in Leeds.

Teachers claim that major changes are being made to their pay, working conditions and pensions and that Michael Gove, Secretary of State for Education, refuses to negotiate with them.

The unions, which represent 90% of Kirklees teachers, claim that the Yorkshire and the East Midlands strike is an action of last resort and is taken with a heavy heart.

NUT joint secretary Howard Roberts said: “We are expecting a very high level of support, but we look upon this with an extremely heavy heart as a sad day.

“Teachers don’t want to strike, it is not what we are in the job for. They are one of the most rational and reasonable groups of people, but the Secretary of State simply won’t negotiate.

He is imposing all of these changes on us which affect teachers and education, what are we supposed to do?

“Mr Gove is driving people away from the profession. It is really frightening that young teachers are leaving the profession in droves.”

He added that in Wales the Education Minister had agreed to negotiate with union leaders and the teachers’ strike had immediately been called off. Today’s strike will be followed by a day of action by London teachers on October 17, after which union leaders will reassess the situation.
