Bosses at the City of Westminster College have announced the potential redundancy of UCU union lead negotiator Keith McKenna.
This follows his timetable being down on hours after some of his classes were switched to other teachers.
UCU members at the college held their largest branch meeting there for years. They voted unanimously to back strikes to support Keith and have also launched a petition.
Workers were set to protest from 12.30pm outside the college entrance in Paddington Green on Wednesday of this week.
