STAFF at Queens University Belfast and Ulster University are to strike for three days next month in disputes over pay and pensions.
Members of the University and College Union (UCU) will walk out between December 1-3 following votes in favour of industrial action.
The strikes will hit 58 universities across the UK before the Christmas break, and alongside both Northern Irish universities, others to join the action will include Cambridge, St Andrews, and King's College London.
UCU general secretary Jo Grady has warned that more industrial action could take place in the spring if the row with employers remains unresolved.
Earlier this month, UCU members backed strike action in two separate disputes, one on pensions and one on pay and working conditions.
Overall, 76 per cent of UCU members who voted backed strike action in the ballot over changes to pensions.
In the ballot on pay and conditions, 70 percent of members backed strike action.
As well as the three strike days, union members will begin other forms of industrial action from December 1.
Dr Grady said: "Strikes over three consecutive days are set to hit university campuses next month unless employers get round the table and take staff concerns over pension cuts, pay and working conditions seriously."
