Teachers at Haringey Sixth Form Centre are threatening to strike over compulsory redundancies being made at the college.
NUT members working at the White Hart Lane centre are balloting for strike action to oppose what they say are unstable employment conditions and declining performance from managerial staff.
Haringey NUT secretary Julie Davies said that members are concerned about falling numbers of students at the college leading to the closure of some courses.
In a letter to 37 union members sent on May 15, Ms Davies said: “We have had concerns about the way staffing is managed at the centre for some time and believe that responding to low take-up of courses by axing them amounts to poor employment practice which threatens our members' ability to plan their lives, careers and finances.
“I would therefore like to meet members to gauge support for a ballot for strike action to oppose this threat to our members in the immediate future and medium term.”
June Jarrett, Principal of Haringey Sixth Form Centre, was unavailable for comment over the half term period. Ms Davies said that the centre’s management had been notified in writing of the ballot.
