Two oil unions in Nigeria, Nupeng and Pengassan, have announced that they will begin an indefinite strike protesting the government?s inability to fix the refineries and cut gas prices. Also the unions are pushing for the passage a new law that will affect oil exportation. This strike could seriously harm the Nigerian economy, as oil exportation is their largest source of revenue.
