The University of Reading has warned it will deduct staff's wages, if they take part in strike action as part of a national dispute.
Issues surrounding pensions, pay and working conditions means some members of the University and Colleges Union (UCU) across 60 universities in the UK have walked-out from their contracted hours.
The university has also threatened to block lecturers' salaries if they fail to reschedule classes missed from the industrial action.

A spokesperson from Reading University said: “Working at a university involves numerous responsibilities to allow us to operate properly.
"We encourage any staff who intend to participate in action short of strike and are unclear on what actions they are entitled to take to speak to their line manager.
“We do not want to dock the pay of any member of staff, but it is important that everyone understands all the implications of their actions.”
