Teachers in the NASUWT union at Sinfin Community School in Derbyshire were set to strike on Wednesday and Thursday of this week.
The strikes are against planned compulsory redundancies.
The school is planning the redundancies while advertising to recruit new teachers.
Headteacher Steve Monks describes it as a “restructuring exercise”.
Dave Wilkinson, NASUWT branch secretary, said, “We cannot sit by
and allow members to be made redundant while the school advertises for more teachers.
“The responsibility for this strike lies with the governing body.”
Teachers at the school successfully stopped plans to turn the school into an academy when NASUWT and NUT union members struck together in 2008.
NASUWT members were also set to walk out at Friesland School in Sandiacre in Derbyshire this Thursday against plans to turn the school into an academy.
The school’s governing body has decided to apply for academy status, which would take the school out of local authority control.
Further strikes are planned for Tuesday and Wednesday of next week.
