Teachers are to take industrial action short of a strike in their bitter dispute with the Government over pay, jobs, pensions and workloads.
The National Union of Teachers and NASUWT said their members will take co-ordinated action from September 26.
The unions said the aim was not to affect pupils, with the action including not attending meetings, filling in forms or covering for absent staff.
Unions said the action was intended to be pupil, parent and public-friendly, whilst resisting Government policies which they said were undermining teachers' ability to work effectively.
Chris Keates, general secretary of NASUWT, said: "The Secretary of State for Education was put on notice in May that he could address teachers' concerns and avoid the possibility of further industrial action.
"At every turn, the Secretary of State shows contempt for the teaching workforce.
"What happens to teachers directly affects the quality of education for children and young people. Teachers and their pupils deserve better."
Christine Blower, general secretary of the NUT, said: "Teachers' morale is dangerously low. Over-the-top accountability measures are exhausting teachers and the idea that they can work to 68 is absurd.
"For the sake of teachers and children's education, these constant attacks from Government need to stop."
