The industrial dispute between the Dangote Petroleum Refinery and the Petroleum and Natural Gas Senior Staff Association of Nigeria took a dramatic turn on Saturday as the union ordered seven branches to cut off crude oil and gas supplies to the $20bn facility. The union’s move marks an escalation in the standoff, with PENGASSAN accusing the refinery of anti-labour practices and the unlawful sack of its members. In the directive issued to its branch chairmen, PENGASSAN instructed its branch chairmen in key upstream and midstream oil companies, including TotalEnergies, Chevron, Seplat, Shell Nigeria Gas, Oando, and Nigerian Gas Infrastructure Company, to immediately cut off all crude oil and gas supplies to the refinery. PUNCH Online reports that the directive comes after PENGASSAN alleged that Nigerian workers were sacked by Dangote Refinery after joining the union, claiming that management also withdrew staff buses and denied entry to locals while allowing expatriates access. As a result, PENGASSAN instructed its branches in TotalEnergies, Seplat, Chevron, Oando, Shell Nigeria Gas, Renaissance, and NGIC to cut gas supply to the refinery immediately.
