The Academic Staff Union of Universities (ASUU) has turned down a request to end its strike.
The union reaffirmed its stance on the strike during a meeting with Federal Government officials in the Presidential Villa in Abuja on Thursday night.
President Muhammadu Buhari's Chief of Staff, Prof. Ibrahim Gambari, had called the union to a meeting in Aso Rock.
The conference, which ended without a truce, was attended by Chris Ngige, the Minister of Labour.
Renegotiation of the 2009 ASUU-FG Agreement and inconsistencies in the Integrated Personnel Payroll Information System are among the others.
President Muhammadu Buhari has urged the union to call off the strike in the students' and nation's best interests.
Professor Emmanuel Osodeke, the Union's Chairman, accused the Federal Government of withholding professors' pay in order to force them back into the classroom.
He expressed the union's determination to continue the strike until its demands were realised.
ASUU's roll-over strike, which began on February 14, was extended for another 12 weeks on Monday.
The funding of public university revitalization, Earned Academic Allowances, the University Transparency Accountability Solution (UTAS), and promotion arrears are among its requests.
