Nigeria's white-collar oil union, PENGASSAN, has said it will begin a "total" strike on Monday aimed at disrupting exports from Nigeria. The DPR branch of PENGASSAN called for the strike to begin on Monday after talks on Saturday collapsed. The strike is designed to disrupt tanker loadings at Nigeria's main export terminals and to disrupt the import of refined products at jetties as union oil workers will not be there to supervise. It is reported that by Sunday all union members will have withdrawn from drilling rigs, export terminals, jetties and depots. Some oil majors such as Shell may use replacement staff to maintain operations at its terminals.
