UCU union members are currently being balloted over new national negotiating structures in the higher education sector. The ballot ends on Monday of next week.
The employers are threatening to withdraw from national bargaining if members do not accept the new structures.
But the deal includes serious restrictions on the ability of UCU members to take industrial action.
The key to defending both pay and conditions and national bargaining in the future will depend on the ability of the union to take action.
Accepting the deal would undermine this.
UCU branches at the University of East London and London School of Economics voted to reject the deal at meetings over the last week.
Activists opposing the deal also pledge to campaign against any management threats to withdraw from national bargaining.
