Buhari endorses new minimum wage
I think there may be some confusion here.
As of my knowledge cutoff, there hasn't been any official announcement or endorsement from President Muhammadu Buhari on a new minimum wage in Nigeria.
However, in 2019, the Nigerian government increased the national minimum wage from N18,000 (approximately $49) to N30,000 (approximately $82) per month, following a long-standing demand from workers and labor unions. This increase was implemented after a tripartite committee comprising government representatives, labor unions, and the private sector agreed on the new wage.
If you're referring to a potential new minimum wage, I'd be happy to help you find more information on any recent developments or announcements from the Nigerian government or relevant authorities.
