Nearly 50 NUT union reps and activists from sixth form colleges met last Saturday.
They unanimously passed a motion calling for an early national strike ballot to fight cuts and defend pay.
Workers at the meeting represented 30 out of 92 sixth form colleges.
The government wants to slash sixth form funding by 12 percent over the next four years.
The union is currently running an indicative ballot.
It asks members to choose between action over sixth form pay alone or to be balloted as part of the national cuts and pensions campaign.
The meeting agreed that teachers should be encouraged to tick both options.
Teachers were assured that this would be recognised by the union’s action committee.
