University strikes: 'We shouldn't have to be out here doing this again'
Staff at Cardiff University and Bangor University have begun an eight-day strike over pay, conditions and pensions.
A member of the University and College Union (UCU) said: "We really shouldn't have to be out here doing this again."
About 60 UK universities are affected by the strikes - they are walking out over increases to pension contributions, casual contracts and a squeeze on wages.
This is the second time in two years UCU members have taken strike action, the first being a 14-day walk-out over pensions in February 2018.
Universities said they had taken steps to protect pensions and pay.
