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.
Hundreds of schools across London could be disrupted today as teachers stage further strike action in an ongoing dispute over pay, pensions and working conditions.
Organisers say 'the overwhelming majority' of teachers from two of England's biggest teaching unions, the NUT and NASUWT, are expected to rally in central London.
The first regional walkout took place in the North West on June 27th, and further strikes took place in East of England, the East Midlands, West Midlands and Yorkshire and Humberside on October 1st.
The Government says it is 'disappointed' at the decision to hold further industrial action.
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.
