The increase in minimum wage has been one controversial issue in Nigeria for some period of time. The past governments that have been in position have made one modification or another as increase to the minimum wage, and the last time it was increased was in 2011 to N18, 000. The law stipulates that the National Minimum Wage be reviewed once every five years, and what ought to have been reviewed in 2016 was not reviewed. This brought up allegations by the Nigerian labour and trade unions for it not being implemented.
