Oau postpones convocation staff strike

I think there may be a mistake here. OAU stands for Obafemi Awolowo University, a university in Nigeria. It's unlikely that OAU would postpone a convocation due to a staff strike, as convocation is a ceremonial event to confer degrees on graduating students.

Could you please provide more context or clarify what you mean by "OAU postpones convocation staff strike"? I'd be happy to help you understand the situation better.
