University strikes: Why staff across the UK are taking industrial action.
Tens of thousands of staff at 150 universities across the UK are on strike again, despite hopes of a breakthrough in talks.
Academic staff are walking out, as are those in other roles including librarians, technicians, security staff and catering workers.
The dispute is over pay, working conditions and pension cuts.
When are UCU university staff striking?
Members of the University and College Union (UCU) are striking on 20, 21 and 22 March.
The UCU initially announced 18 days of industrial action during February and March. It called off some of those dates after making "significant progress across a range of issues".
A revised offer was then made by employers in the dispute, but the union decided not to consult on it formally with its members.
The union has said it will re-ballot staff at 150 universities about further strike action if there is no resolution.
UCU staff also walked out in November 2022. Industrial action has been taking place at some universities since 2021.
Which universities are involved?
UCU members at 83 universities are striking over pay and working conditions, five are striking over pensions and 62 are striking over both issues. You can read the full list here.
Unison members are striking on 20 and 21 March at Glasgow School of Art and Queen Margaret University and on 25 April at Arts University Bournemouth, after walking out in February.
Unite and EIS have also been on strike but do not have any further dates scheduled.
When are the next strikes and what pay do workers want?
Are you affected by the dispute?
Are lectures being cancelled?
The Universities and College Employers Association (UCEA) says the strikes have caused "low and isolated" levels of disruption to students.
Universities UK (UUK), which represents 140 institutions, said some universities have extended coursework deadlines and rescheduled teaching.
If students feel the measures put in place are not good enough, they can use their university's existing complaints procedure.
The UCU says 70,000 staff have taken part in the strikes and they have been "overwhelmed by the support of thousands of students" who have joined.
Why are university staff striking?
Most staff are striking over pay and conditions.
For the 2022-23 pay round, the unions have asked for:
a pay rise worth either the RPI measure of inflation +2%, or 12% - whichever is higher
action to end the use of zero hours and temporary contracts
The unions said they were offered an improved pay deal for 2023-24 worth between 5% and 8% on 25 January, but this was a real-terms "pay cut".
The UCEA said it would begin implementing that 2023-24 pay uplift in March, despite talks stalling without an agreement on pay.
The UCU said progress had been made "across a range of subjects".
Some UCU members are also striking over pensions.
