Mr Bede Opara, the President of the union, disclosed this in a telephone interview with the News Agency of Nigeria (NAN) in Lagos.
He said that the suspension followed the outcome of last Friday’s meeting with Chief Emeka Wogu, the Minister of Labour and Productivity.
The union planned to embark on the strike to protest the recent sack of three top officials of the Transmission Company of Nigeria and the PHCN.
Opera said that the minister had scheduled another meeting with all PHCN unions on Friday to fashion out ways to address the crisis in the power sector.
“The proposed strike has been put on hold pending the outcome of the Minister of Labour meeting with all the unions,” he said, adding:
“That the strike has been temporary put on hold does not mean it will not hold, but we have to obey the appeal of the minister of labour.”
