UCU union members at Lewisham and Southwark College were set to begin a two-day strike on Thursday of this week.
The workers face cuts that put up to 200 jobs at risk and could see an entire campus, in Camberwell, close down.
The cuts would close down the college’s trade union studies department.
The walkout follows a successful 24-hour strike earlier this month.
One UCU member told Socialist Worker, “Further education isn’t being funded—it’s not on the agenda.
“We are going to have to do a ‘skills match’ then an interview to try and keep our jobs. It’s awful.
“But we’ve been recruiting people to the UCU during this dispute.”
Another worker said, “Once we started striking you saw a mood change. It made people make decisions about where they stood.
“If you’re under 40 you haven’t seen workers win anything significant in your lifetime. Some people asked what a picket line was.
“People are being politicised at our college.”
UCU members at the college backed strikes by 85 percent in a recent ballot.
UCU members at Ealing, Hammersmith and West London College were set to join the strike for 24 hours on the Thursday.
Those at Hackney College planned to walk out for one hour on the same day.
