Ibrahim Nock and his supporters split away at the end of 1962 to form the Northern Federation of Labour, while early in 1963, Wahab Goodluck and S. U. Bassey took over the leadership of the IULC, which they renamed as the NTUC.
In 1968, a small group led by E. Bussey Etienam broke away to form the Nigerian Federation of Labour.
