Addressing the press at the senior staff canteen, Louis Kakinda, the spokesperson of the staff, said they would not settle for anything less than 100%.
The vice-chancellor, Prof John Ssentamu Ddumba, on Thursday said the university had reallocated sh20b to staff salaries, which would enable a 20% raise.
He said the money was initially assigned to travel, workshops, allowances, lubricants and roads.
But the staff insisted that the university council fulfills an earlier promise of a 'handsome pay raise' effective this financial year.
"We do not care where and how the council finds the money to implement the 100% pay increment," said Kakinda.
In May, the council endorsed a 100% pay raise for all Makerere staff, only for the idea to be rejected by the finance ministry over resource constraints.
The staff later met the university council, but both parties only said they were back to negotiations, without giving details.
Makerere staff laid down their tools over a week ago, over the demand for a pay raise and the council closed the university.
Education minister Jessica Alupo subsequently ordered the council to open the university within two weeks, saying the Government did not have the money to bankroll a pay raise.
Makerere is currently chocking on a sh67b debt, most of it accruing from pension arrears.
