Workers at Lambeth College remain in dispute over hated new contracts.
The contracts slash holidays and impose longer working hours, among other attacks.
UCU union members at the college struck for over five weeks against the contracts last term.
Unison union members also struck for three days.
Workers are deciding their next move in the dispute.
UCU union members at Barnsley College are balloting for strikes over a restructure that left many without jobs or on lower pay.
The ballot ends on Monday of next week.
Reballots have opened the way to bigger struggle
