The Nigeria Union of Petroleum and Natural Gas Workers, NUPENG is set to begin a three-day nationwide warning strike on Wednesday, over disputes with international oil companies.
The main issues centre on indiscriminate sack of workers without benefits and refusal to allow their workers to join union.
The union has been having running battles with some oil companies, including Exxon/Mobil and Chevron Nigeria Limited, over unfair labour practices, sack of workers without benefits, breach of Nigerian extant labour laws in their divestment exercises. 

Meanwhile the Nigerian National Petroleum Corporation, is blaming oil marketers in the country for the scarcity of kerosene and cooking gas and the high price of the commodities across the country.
The price of cooking gas had shot up from about N3, 500 before the Christmas holidays, to a minimum of N5, 000 for a 12.5 Kg last week, while kerosene which went for as much as N250 per litre is now sold for a minimum of N500
