The Nigerian Union of Teachers (NUT) in Kaduna State has issued the State Governor, Nasir El-Rufai, a two-week ultimatum to rescind his decision to sack over 21,000 teachers.
The affected teachers were said to have failed the recent competency test conducted for primary school teachers in the state.
The union said if the governor refused to rescind his decision, it will commence an indefinite strike action.
Daily Trust reports that the notice was served via a letter to the governor and takes effect from yesterday November 6 to November 23, 2017.
The Assistant Secretary General of the union, Comrade Adamu Ango, who signed the letter, said at the expiration of the ultimatum, the union would embark on an industrial action in compliance with the wishes of its members expressed at the meeting of the state executive council which was held yesterday.
