NUT union members at Listerdale Primary School in Rotherham, South Yorkshire, were set to begin industrial action over workload this week.
Teachers will also begin a strike ballot over the suspension of an NUT member at the school.
The action short of a strike was set to begin on Thursday of this week. It follows bosses’ plans to impose job cuts and cut the hours of teaching assistants and school support workers.
This will push up teachers’ workload and harm children’s education.
The Children’s Academy Trust runs the school. The NUT said the chair of the trust has refused to meet the union.
Campaigners (pictured) handed in a petition against tests for young children to the Department for Education on Thursday of last week.
The Tories want to force children as young as four to undergo “baseline assessments” when they are in reception classes. Nearly 10,000 people signed the petition against the plan.
Teachers were set to lobby supply agencies in London on Wednesday of this week.
The action, organised by the NUT union, aims to highlight the “unacceptable pay and pensions position” supply teachers face.
