Hundreds of college lecturers, including lecturers from Bradford College, are to stage a two-day strike in a dispute over pay, with more set to be balloted for industrial action.
Members of the University and College Union (UCU) at six colleges in England will walk out from November 28.
Ballots of UCU members at 26 more institutions will open on the same day, with the result due on December 19.
The union says it has been waiting months for a decent wage offer, adding that college staff have seen their pay decline by 25% over the past decade.
UCU officials said that while the Chancellor found £400 million for "little extras" for schools in his Budget, there was no new funding for colleges.
UCU head of policy and campaigns Matt Waddup said:
Staff in further education colleges have seen their pay systematically eroded in recent years and are being paid £7,000 less than school teachers.
Around 700 staff will be on strike next week including staff from: Bath, Bradford, New College Swindon, Croydon, Lambeth and Petroc in Devon.
