Teachers at Fortismere School in Muswell Hill are threatening to strike following allegations of bullying in the workplace.
Fortismere’s NUT members are currently voting on whether to take strike action after 52 members supported calls for an indicative ballot at a union meeting last month.
Concerns have been raised over inconsistent pay scales, unfair recruitment procedures, excessive workloads, and “harsh” treatment of union members.
In a letter to members, Haringey NUT secretary Julie Davies wrote: “The list of problems at Fortismere is a long one and it has been growing for some time.
“Our recent survey produced a large number of criticisms of basic management in the school and there is evidence of bullying.”
Helen Anthony, the school’s headteacher, has also been accused of holding an “anti-NUT assembly”, in which she asked children to tell her the difference between fact and fiction in relation to a newspaper article concerning her.
The incident caused the NUT to make a formal complaint to the school’s governors.
In response to the threatened strike action, Ms Anthony said: “I consider myself to be very fortunate to be the Head of Fortsimere School and could not wish for better staff.
“At this critical time for our students, I know that the prime focus is on ensuring the best possible outcomes for them and my staff are totally committed to that.
“We already have a meeting scheduled with the NUT for May 19, which will be the appropriate time at which to discuss any concerns.”
The NUT's voting will close on May 19.
