Workers on strike at 9 oil refineries producing 10% of US fuel
Workers at nine US oil refineries and chemical plants across four states, producing some 10 percent of the country’s fuel, went on strike after their union announced that negotiations on their salaries and safety concerns failed.
The mass walkout of refinery workers – the first since 1980 – took place on Sunday, after the United Steelworkers union (USW) rejected the fifth offer by the industry’s main negotiator, Royal Dutch Shell Plc, which in turn halted talks.
“Shell refused to provide us with a counter-offer and left the bargaining table," USW International President Leo Gerard said. "We had no choice but to give notice of a work stoppage.”
