The Academic Staff Union of Universities (ASUU) has extended its ongoing strike by another 12 weeks.
A statement signed by ASUU president, Prof. Emmanuel Osodeke, said this will give the government enough time to resolve all the issues at stake.
It also stated that the extension was effective from 12:01 am, 8 May.
ASUU took the decision after its National Executive Council meeting which started Sunday night in Abuja.
The union had been on a warning strike since February, over welfare issues.
The long strike has led to protests by students who are calling for classes to resume.
Last week the National Association of Nigerian Students (NANS) threatened to organise a massive protest in Abuja.
