There appears to be no end in sight to the fight between oil workers and America oil multinational, Exxon Mobil.

On Friday, the oil workers under the auspices of Petroleum and Natural Gas Senior Staff Association of Nigeria, PENGASSAN called for the shutdown of all Exxon Mobil Corp facilities in the Niger Delta.

PENGASSAN’s chairman in Rivers State, Madubuezi Azubuike, said the call for the shutdown followed the breakdown of talks with the company.

The union and the company had been in talks over some 150 workers who were sacked in December last year, and had called a strike which the government came in to mediate.

The mediation talks had failed.

"We have called for the shutdown of all Mobil facilities across the Delta today. No resolution has been reached so far. We have had meetings with top management of the union and Mobil executives, but with no avail over issues," Azubuike said.

An Exxon Mobil spokesman was not immediately available for comment.

Strikes by Exxon workers in Nigeria at the end of last year did impact output, delaying loadings by weeks.
