Teachers at Langdon School in Newham, east London, were set to strike on Wednesday and Thursday of this week.
The action, by NUT union members, is over oppressive management and workload.
The union had suspended a planned two-day strike for talks at Acas, but these failed to resolve the dispute.
Peter Smith is divisional secretary of Newham NUT. He told Socialist Worker, “We spent all day at Acas talks on Monday 17 October, at the request of the school.
“At no stage did management put forward a resolution. The only resolution came from us.
“We felt we were close to an agreement. We sent a draft joint statement to the local authority and then a letter.
“We had no response—and then found out that four of our members had been suspended. There is no alternative but to strike.”
Teachers at the school struck in July this year.
Management suspended the four NUT members last week, alleging professional misconduct. All four have struck previously. Many believe a union-busting agenda lies behind the dispute.
Nick Grant, a member of the NUT’s national executive committee, told Socialist Worker, “The NUT will back its members at Langdon all the way until this dispute is won.
“There is no excuse for the bullying and random diktats that our teachers are facing. Managers hell-bent on confrontation with unions have ditched six months of talks.”
Strikes against bullying in other schools, such as Villiers High School in Southall, have scored great victories. Action at Langdon can do the same.
