Asuu commences nationwide warning strike

I think there may be some confusion here.

ASUU stands for Academic Staff Union of Universities, which is a trade union in Nigeria that represents the interests of university lecturers and academics. While ASUU has indeed gone on strike several times in the past, I'm not aware of any current nationwide warning strike.

If you're referring to a specific news article or report, could you please provide more context or a link to the article? I'd be happy to help clarify the situation.
