Around 4,000 staff at 31 colleges will take up to 10 days of strike action starting next week in a dispute over low pay amid the cost-of-living crisis.
Staff at 20 colleges across England begin their strike next Monday 26 September with a further nine colleges striking the week after.
The level of industrial action being undertaken is 'unprecedented' in England, UCU says.
Staff will be picketing outside every college on each morning of strike action. The strikes will take place over four weeks in the first half term of the academic year.
