There seems to be more trouble brewing for Nigeria’s education sector.

Polytechnic lecturers under the umbrella of the Academic Staff Union of Polytechnics have threatened to withdraw their services and commence a comprehensive and indefinite strike action if the federal government fails to address their grievances within 21 days.

The notice was contained in a letter sent to the Ministry of Labour and Employment.

The ultimatum takes effect from October 9 and ends on October 30.

In the letter, the lecturers also threatened to withdraw from the negotiation of its 2010 agreement with the government.

Some of the issues the lecturers say must be addressed include the amendment bill of the Polytechnics Act, the non-payment of staff salaries in some state-owned institutions, and the non-release of CONTISS 15 Migration Arrears.

The letter signed by the National President of the Union, Comrade Usman, Y. Dutse was copied to the Executive Secretary, National Board for Technical Education and the Chairman, Federal Government/ASUP 2010 Renegotiation Committee.

“The NEC of our union reviewed the progress made by the government in resolving issues bordering on the welfare of its members and smooth functioning of the sector. NEC specifically discussed the outcome of the meeting between our union and the Honorable Minister of Education on the 22nd of August, 2017" the letter read.

“The Honorable Minister had at the meeting, assured the union that within one month, the issues presented by the union would have been addressed. You may also recall sir, that our union withdrew the services of its members in a one week warning strike in February, 2017 over same issues.”

The strike warning comes less than three weeks after the government solved its own discrepancies with university lecturers.

The Academic Staff Union of Universities had on September 20 announced a conditional suspension of its strike action.

The body has, however, insisted on some conditions, which it has given the government a deadline to meet or else it will embark on another strike.

The deadline given by ASUU expires at the end of October 2017.
