WORKERS building a third production unit at a multinational liquefied natural gas plant in southern Nigeria have gone on strike over a locally-imposed levy, the company said. A spokesman for the operating company Nigeria LNG, co-owned by Anglo-Dutch oil group Royal Dutch/Shell, Italy’s Agip, French group Totalfina Elf and the state-run Nigerian company NNPC, said the strike began last week. The action is protesting a levy imposed on workers’ salaries by the government of Rivers State, where the LNG plant is situated, newspaper reports. – AFP
