Staff at 150 universities across the UK are taking part in a series of strikes.
The action is being taken over pay, working conditions and pension cuts.
They will be walking out on three days - 24, 25 and 30 November.
Staff in England, Wales and Scotland will also begin industrial action short of a strike from 23 November, and in Northern Ireland from 18 November.
This will include not covering for absent colleagues, refusing to make up for work lost to strike action and working to rule.
A series of strikes were also held earlier this year and last year.
