Cambridge: Striking Teachers March In City
Hundreds of striking teachers have marched through Cambridge.
The National Union of Teachers says that up to 500 teachers staging industrial action were involved in a march through the city, followed by a protest outside the Guidlhall.
Around 100 schools across the Cambridgeshire and Peterborough area were affected by the walk-out, in the ongoing row about pay, workloads and pensions.
Some were forced to close, while others had to cancel lessons.
Tom Woodcock, from the Cambridgeshire branch of the National Union of Teachers, told Heart: "We're taking strike action today because teachers are far too over-worked, and because of the teaching conditions of our staff and learning conditions of our students.
We don't want people to be learning in an environment where teachers are totally over-worked, under-paid, and teaching a curriculum not fit for purpose."
The action was condemned by the Department for Education which says that it will disrupt parents' lives and damage children's education.
NUT general secretary Christine Blower said: "Certainly the message we are getting is that the action is well-supported.
On the back of the 60-hour week workload diary survey teachers are just feeling overwhelmed.''
She said rallies and marches are taking place all over the country and that "people will be out and about''.
Ms Blower said the NUT has been staging events around the country on a weekly basis for some time to tell the public about their campaign and the issues they are highlighting.
"We are saying that very bad things are happening to education and (Education Secretary) Michael Gove needs to listen.''
The NUT's bitter dispute with the Government focuses on three issues - changes to pay, pensions and workload.
The DfE has said parents will "struggle to understand'' why the NUT was pressing ahead with its strike.
A spokesman said: "They called for talks to avoid industrial action, we agreed to their request, and talks have been taking place weekly.
Despite this constructive engagement with their concerns, the NUT is taking action that will disrupt parents' lives, hold back children's education and damage the reputation of the profession.''
Yesterday, David Cameron's official spokesman said the Prime Minister would call on teachers not to strike because the action "disrupts children's education and children's families''.
Mr Gove yesterday wrote to seven union bosses setting out the progress he believed had been made in talks between the DfE and teaching unions.
In it, he said he wanted to underline his commitment to the talks process, but the NUT said the letter showed how little progress had been made in the talks.
The NUT has been embroiled in its dispute with the Government for more than two years, and staged a series of regional strikes with the NASUWT teaching union last year.
Between them they represent the vast majority of teachers.
A proposed one-day national walkout in November by the two unions was called off and the NASUWT decided not to take part in today's strike.

360 businesses have been named and shamed for underpaying thousands of workers a total of almost £1million.
A homeless man in Cambridge, who saw a student set fire to £20, has told Heart the 18-year-old "deserves to be kicked out of University."
