According to a statement issued by the Vice-Chancellor, Prof. Michael Adikwu, on Sunday, the warning was in compliance with the directive from the Federal Government.
Adikwu listed the unions as the local branches of Academic Staff Union of Universities (ASUU), Senior Staff Association of Nigerian Universities SSANU) and Non-Academic Staff of Nigerian Universities (NASU).
He called on the striking staff to return to work without further delay in the interest of the growth and stability of the university.
It would be recalled that some labour unions on May 18 embarked on strike following the breakdown in negotiation and expiration of their ultimatum to Federal Government to reverse the increment in petrol price.
