Government reforms will leave teachers overworked and under-qualified, a striking teacher has told Daybreak.
History teacher John Boniface said reforms would be "attacks" on the "education they are going to be able to provide for children".
He criticised plans to allow teachers without a proper qualification to work in a classroom and not giving teachers enough time to plan lessons.
Schools across the region are closed as part of a national strike by teachers.
A mass rally's due to be held on College Green in Bristol by staff protesting about increased workloads, pension changes and plans to bring in performance related pay.
Almost three-quarters of people are opposed to the teachers strike, according to the Department of Education
A spokeswoman said 70% of people were against industrial action or believed teachers should not be allowed to strike at all.
The teachers' unions argue their members are walking out because of cuts to their pay, higher pension contributions and poor working conditions.
Teachers are going on strike because of they will be forced to pay more into their pensions, work for longer and get less out when they retire, their unions have said.
According to the the National Union of Teachers (NUT), thousands of schools will be shut down because:
- Schools will be allowed to set teachers' salaries, according to their performance in the classroom.
- Pay rises are capped at 1%.
- Teachers will have to make higher pension contributions.
- Unions say this will leave their members with a 15% pay cut, as inflation rises beyond 1% and teachers are forced to put more into their pensions each month.
- They also accuse the Government of attacking their working conditions, including allowing schools to have longer school days and longer terms.
Thousands of pupils across England will miss a day of school as their teachers go on strike in a row over pay, pensions and conditions, their unions have announced.
The National Union of Teachers (NUT) and NASUWT say members are fed up with Government reforms which will cut deeper into salaries and force staff to work longer, while pensions pay out less.
Pupils in four regions of England - the North East and Cumbria, the South West, South East and London - will be affected, as members of two of England's biggest teaching unions take part in the second day of walkouts this term.
NASUWT general secretary Chris Keates said the "overwhelming majority" of teachers in these regions would be on strike and blamed education secretary Michael Gove for the industrial action.
"It is the failure and unreasonableness of the Secretary of State, who day-in-day-out is disrupting the education of children and young people through his attacks on the teaching profession."
More than 1,000 people attended rallies in London and Nottingham to protest against the government’s education policies.
"The message that's coming through is that we have a secretary of state who's not listening. He's not consulting properly and is just driving through his own personal agenda", Chris Keates, general secretary of the National Association of Schoolmasters Union of Women Teachers, said in Nottingham.
Speaking to a crowd of 700 people at the Westminster event, NUT general secretary Christine Blower said the rallies presented a “positive vision and voice for education”.
"This is in stark contrast to the coalition Government whose continual denigration of our schools, teachers and pupil attainment has caused widespread dismay,” she said.
Tens of thousands of children are missing lessons today as teachers stage a one-day strike over pay, pensions and conditions.
Members of the National Union of Teachers (NUT) and the NASUWT are taking part in industrial action across the North West.
Around 2,765 schools in 22 authorities are affected by the walkout, the unions have claimed.
As part of the action, rallies are being held in Liverpool, Manchester, Preston and Chester.
NASUWT general secretary Chris Keates said the teaching profession is in "crisis" following "three years of attacks by the Coalition Government".
Teachers' unions have announced a rolling programme of regional strikes over the next few months, affecting schools across England and Wales.
It is thought the action could be followed by a national walkout in the autumn over a dispute on pay, pensions, working conditions and jobs.
Education Secretary Michael Gove said in a letter to both unions in March that he was wrote willing to meet them to discuss their dispute, but also insisting that the "direction of travel" on both of their key issues is "fixed".
From this autumn, teachers' pay will be linked to performance in the classroom, with schools setting salaries, rather than following a national framework.
More than 2,500 schools in the North West of England could be affected today as teachers stage a walkout over pay, pensions, working conditions and jobs.
Members of the National Union of Teachers (NUT) and NASUWT will take part in a strike, the first in a planned national rolling programme of strikes across England and Wales which will continue in the Autumn term.
Twenty two authorities, and a possible 2,765 schools, across the North West will be affected as joint rallies are held in Liverpool, Manchester, Chester and Preston.
Chris Keates, General Secretary of the NASUWT, will address the rally in Liverpool at midday.
A Department for Education spokeswoman has insisted that teaching is an attractive profession.
She said the coalition's reforms gave schools "more freedom" with an education system that matched "the world's best". She added:
