Staff at the University of Stirling are walking out, in a dispute over pay and pensions.
Members of the UCU staged industrial action last week, and will also strike tomorrow.
They're joining workers at 150 UK universities.
Talks are continuing in a bid to settle the dispute - with hopes an agreement can be reached.
UCU general secretary, Jo Grady, said: “This breakthrough is down to the strength, determination and sacrifice of university workers who have stood on picket lines. The proposals will now move through our union’s democratic processes, and strike action will continue until our 70,000 UCU members have had the chance to have their say.”
