The Petroleum and Natural Gas Senior Staff Association of Nigeria (PENGASSAN) has ordered its members nationwide to immediately suspend the supply of gas and crude oil to the Dangote Refinery. The directive was contained in a letter dated Saturday and signed by the union’s General Secretary, Lumumba Okugbawa, addressed to its branch chairmen across the country. According to PENGASSAN, the move follows the refinery’s termination of over 800 workers. Consequently, the union instructed members to cut off gas supply to the Nigerian Gas Infrastructure Company Limited, close all crude oil supply valves to the refinery, and stop loading operations for any vessel bound for the facility. “We bring you fraternal greetings from the National Secretariat. As you are aware, the management of Dangote Petroleum Refinery has disengaged our members in reaction to the exercise of their constitutional right to be unionised. “They have gone further on a mission of misinformation and propaganda to justify this illegitimacy rather than engaging meaningfully with us to right the wrong. “Consequent to these, you are hereby directed to cut off gas supply to NGIC effective immediately. All crude oil supply valves to the refinery should be shut. The loading operation for the vessel headed there should be halted immediately. “NGIC Chairman, ensure that gas supply to the refinery is cut off effective immediately. “All chairmen on this summons are to report promptly the progress of the directive. Kindly accept the assurances of our highest esteem. Thank you. ‘Injury to one, injury to all,’” the letter reads. The move comes as a direct reaction to the 650,000-barrel-per-day refinery’s dismissal of 800 workers following their decision to voluntarily join PENGASSAN. This development follows Dangote’s confirmation that the affected employees were terminated over alleged “sabotage.” On Friday, WAFFI TV had reported that the refinery laid off all its Nigerian staff after they joined the union. PENGASSAN President, Festus Osifo, in an interview with DAILY POST, insisted that every dismissed worker must be reinstated by the refinery.
