The Joint Action Committee (JAC) of Non-Academic Staff Union (NASU) and Senior Staff Association of Nigeria Universities (SSANU), yesterday, threatened to ground universities in the country should the Federal Government fail to fulfil its demands, including a N40 billion payment. To show seriousness, the two unions have begun a three-day nationwide warning protest in response to government’s alleged failure to address any of the issues contained in the memorandum of understanding (MoU) signed by both parties in recent years. At the University of Ibadan (UI), the JAC of both unions converged on the main gate of the institution, marching through the Administrative Block, which houses office of the vice chancellor.
