Workers at the University of Liverpool were set to protest outside the honorary graduates celebration dinner on Wednesday of this week.
The university made a shock announcement last month that it would issue dismissals notices to 2,803 staff to force new and inferior contracts.
Mass union meetings have voted for industrial action and the UCU, Unison and Unite unions are all now balloting for strikes.
Some 200 people joined a rally last week.
More than 4,000 have signed an online petition against the University’s action and 600 professors signed a letter of protest in the Times Higher Education.
At an open meeting with staff the vice-chancellor confirmed that any worker who does not sign the new contract will be dismissed.
This could set a precedent across the sector, so UCU has declared Liverpool a “dispute of national importance”. A further mass meeting was planned on Tuesday organised by UCU but open to all staff.
All three unions are working together to get the threat of dismissals lifted.
They plan leafleting and further protests.
