Kogi West Senator, Sunday Karimi, has warned the Petroleum and Natural Gas Senior Staff Association of Nigeria, PENGASSAN, to respect the Petroleum Industry Act, PIA, saying the union’s directive to withdraw services affecting the Dangote Refinery risks damaging the economy and deterring investors. The directive covered control-room and panel operations, outfield personnel and other services across companies, agencies and institutions, and specifically called for the immediate suspension of processes involving gas and crude supply to the Dangote Refinery. Karimi contrasted the situation at the refinery with other privately run sectors where union activity is limited. Union activity is also restricted or disallowed in other industries such as aviation, tourism and electricity, where private investors are dominant. Karimi contrasted that privately built refinery — now one of the world’s largest single-train refineries — with government-owned refineries that have continued to incur huge maintenance costs.
