Staff at both Sheffield universities are launching a two-day strike from today over pay and conditions.
Picket lines will take place at Firth Court and the Hicks building at the University of Sheffield, and at Sheffield Hallam there will be pickets at the Owen, Cantor and Collegiate buildings from 8am.
UCU members will also attend a rally at Sheffield Cathedral from 1.30pm on Thursday, with speakers including UCU president elect Rob Goodfellow.
Staff will also begin working to contract from Wednesday, which means they will refuse to work overtime, set additional work, or undertake any voluntary duties like covering timetabled classes for absent colleagues.
If no agreement is reached in the coming weeks, members have agreed to further strike action targeting open days and graduation ceremonies.
