Staff at Sheffield’s two universities are set to walk out on Tuesday, December 3, for a second national one-day strike in support of a pay claim.
Three unions – Unison, Unite and UCU – which took similar action at the end of October are again to join forces.
Some Sheffield lecturers have also been taking part in other forms of industrial action by working to contract.
A Hallam UCU spokesman said staff were boycotting weekend open days and not responding to emails outside working hours.
He said a further strike was planned for the new year unless university employers were prepared to enter into negotiations.
Both Sheffield universities stayed open during the first strike though some lectures were cancelled and services had to be suspended.
In December the three unions will also be joined by the Scottish education union, the EIS.
Union members are angry at a one per cent pay offer, which they claim is effectively another cut after their wages have fallen 13 per cent over the last few years.
University employers say nine out of 10 institutions across the country reported ‘no-to-low’ impact from the day of action on October 31.
