The majority of schools in Waltham Forest are expected to close next week as teachers strike over pay and pensions, the National Union of Teachers (NUT) has said.
Member of the NUT in Waltham Forest are set to walk out on Wednesday as part of an on-going dispute with the coalition govenment over education reforms.
Education Secretary Michael Gove is pushing to introduce new performance-related pay, which he says will improve efficiency, and make changes to pensions.
Waltham Forest NUT secretary, Steve White, said: "Teacher workload is unsustainable and the thought of doing the job until 68 is driving many away from the job.
"Teacher morale is at dangerously low levels. Children need teachers who are fresh and well motivated not tired and demoralised.
"All the polls show that Michael Gove is out of touch with teachers and parents – he must listen and change direction.
"This strike is his fault - teachers do not like taking strike action but they are prepared to lose pay to stand up for education.
"We do apologise for the inconvenience to parents but we hope they will support us."
