Relationship between oil firms in Nigeria and their workers are turning sour.

The workers, under the aegis of the Petroleum and Natural Gas Senior Staff Association of Nigeria (PENGASSAN) has given some of the oil firms a 21-day ultimatum over anti-labour practices.

PENGASSAN’s Public Relation Officer, Fortune Obi said some of the oil companies on its watch-list are Fugro, Sterling Global, Indorama Petrochemical Company, Baker Hughes and General Electric.

Others are Universal Energy, Frontier Energy, Vam Onne, Neconde Energy and Obi Jackson Group, SDF, Ciscon, Tecon, Obax, Pan Ocean, NNPC Retail Limited, ExxonMobil and Petrobras.

Obi said that the decision to go on strike after the 21-day ultimatum, was reached at a meeting with the Central Working Committee of the union.

He made this known on Sunday in Calabar, the Cross River state capital.

“The union gave the ultimatum due to persistent unfair industrial relations practices by the management of the companies in the sector,’’ he said.

But what are these anti-labour issues, you may ask?

According to Obi the oil firms sins are:

1. Sustained indiscriminate redundancies

2. Illegal sack

3. Casualisation and ill-treatment

4. Adverse work conditions

5. Incessant disagreement to collective bargain resolutions.
