Thousands of university staff are “absolutely burnt out”, a union official said as thousands walked out in a second day of strike action in Scotland.

Around 8,000 lecturers, librarians and researchers who are members of the University and College Union (UCU) continued their 48-hour walkout on Friday in an ongoing dispute over pay, pensions and conditions.

The UCU said many of its members are employed on precarious contracts which does not give them enough time for marking or supporting students.

The union also claims members have lost 35% of their expected pension income after cuts were made to the Universities Superannuation Scheme (USS).

Speaking to BBC Radio Scotland’s Good Morning Scotland programme on Friday, UCU Scotland’s Mary Senior said staff are “burnt out” given their current conditions, adding: “Hundreds of university staff in Scotland are on short-term, fixed-term and hourly paid contracts.

“Their pay has lost value by 25% since 2009. They are faced with unsafe workloads and precarious contracts in the sector.

“Those on hourly paid contracts aren’t often paid for the time to mark essays or to provide the extra support students need.

“We really are in an unsustainable situation.

She claimed the pension scheme has a £1.8 billion surplus and cuts of more than a third have been made.

“You can see why our members are so angry and that’s why we had strong picket lines yesterday and we’re expecting the same today,” Ms Senior added.

Students will see disruption while strikes are ongoing as they gear up for exams and assessments in the coming weeks, but Ms Senior said the UCU has been “heartened” by the support it has received from students.

“It’s deeply regrettable, workers come into the university sector to support students, to provide them with education,” she said of the strike action.

“We’ve been really heartened by students who have joined us on the picket lines.

“They know our working conditions are their learning conditions.”

University staff had a 3% pay offer “imposed” on them, Ms Senior said, but she warned with inflation in double figures, that “doesn’t cut it”.

Speaking to the PA news agency at a joint rally held between the UCU and the EIS teaching union, Ms Senior urged universities to get back to the negotiating table.

“Employers really do need to revoke those pension cuts and they need to come back with an offer that acknowledges the cost-of-living crisis that we’re currently living in and addresses insecure contracts, workloads and equality issues in the workplace,” she said.

In recent years, Scottish universities have been forced to lean more heavily on international students due to the fixed funding they receive for domestic students.

When asked if an increased offer to lecturers could have a knock-on effect on the number of Scottish students at university, Ms Senior said “we know the money is there and they can do better”, adding that her union will campaign alongside institutions for more funding from Government.

Employers say they are taking steps to mitigate disruption, adding the union is seeking an “unrealistic” 13.6% pay rise which would cost institutions around £1.5 billion.

Professor Steve West, from Universities UK, said: “We’re trying to do everything we can within the environments we’re operating with the funding we’ve got to make sure we are fair and transparent in the way we support our staff.

“My number one priority at the moment is to ensure we don’t disadvantage students.

“Frankly they’ve had a really difficult time over the last few years with Covid. This is the last thing they need.”

Meanwhile, postal workers who are members of the Communication Workers Union (CWU) also walked out again on Friday in an increasingly bitter dispute over pay and conditions.

In an article for The Independent, CWU general secretary Dave Ward wrote: “The reason for today’s strike is simple: it’s about stopping the Uberisation of Royal Mail. The management agenda is about Royal Mail being transformed into a gig economy-style parcel courier, with a business model reliant on bogus self-employment and casual labour.

“For employers, the decent conditions and job protections our members enjoy seem to be a downside to running the company, which turned a £758 million profit last year.

“The other obstacle is the CWU, who they rightly see as a serious obstacle to this levelling-down agenda.”

Royal Mail chief executive Simon Thompson said: “Talks have lasted for seven months and we have made numerous improvements and two pay offers, which would now see up to a 9% pay increase over 18 months alongside a host of other enhancements. This is our best and final offer.

“Negotiations involve give and take, but it appears that the CWU’s approach is to just take. We want to reach a deal, but time is running out for the CWU to change their position and avoid further damaging strike action tomorrow.

“The strikes have already added £100 million to Royal Mail’s losses so far this year. In a materially loss-making company, with every additional day of strike action we are facing the difficult choice of whether we spend our money on pay and protecting jobs, or on the cost of strikes.

“The CWU’s planned strike action is holding Christmas to ransom for our customers, businesses and families across the country, and is putting their own members’ jobs at risk.”
