The Minister of Labour and Employment, Chris Ngige, and the Trade Union Congress disagreed on Wednesday over the plan by the TUC to go on strike as from September 23.
The minister while answering questions from State House correspondents at the end of the weekly meeting of the Federal Executive Council at the Presidential Villa, Abuja, dismissed the seven-day ultimatum the TUC gave the Federal Government to reverse the price of petrol.
According to him, the letter written by the TUC should have been addressed to him, instead of the President, Muhammadu Buhari.
But the TUC President, President, Quadri Olaleye, said the issue of petrol price was beyond the minister, adding that Ngige should wait till September 23 to see what would happen.
Also, on Wednesday, the Nigeria Labour Congress issued a two-week ultimatum to the Federal Government to reverse its decision on the hikes in electricity tariff and the fuel pump price or face civil unrest nationwide.
The congress handed down the warning at its Central Working Committee meeting in Abuja on Wednesday.
In a communiqué read by the NLC President, Ayuba Wabba, the union said the ultimatum would take immediate effect, warning that it would mobilize its members nationwide for protests as from September 28.
