Thousands of workers at state-owned oil, gas and petrochemical companies in Kuwait will stage a strike from Sunday in protest at a government plan to cut some of their benefits and wages, the president of the oil and gas union said on Monday. "The union finds itself obliged to take the difficult decision to escalate with this announcement of a general strike in all sectors (of oil and gas) starting on Sunday 17 April at 7am (0400 GMT)," Saif al-Qahtani, head of the Oil and Petrochemical Industries Workers Confederation, told a news conference. The union did not say how long the strike would last. Production and exports would not be affected by the strike, a spokesman for Kuwait's national oil company Kuwait Petroleum Corp (KNPC), one of five state-owned companies that will be affected by the strike, said. "If the strike happens we have a strategy in place to deal with this kind of action where extra staff will be used to run operations" Khaled Al-Asousi, KNPC's Deputy CEO for Support Services said, adding that some oil facilities might be shut down temporarily.
