French oil giant Total's workers from Fort-Mardyck refinery listen to unions representatives during a general assembly on February 24, 2010 in Fort-Mardyck near Dunkirk, northern France, before deciding whether or not they will continue their strike to prevent the closing of the site. The group's striking refinery workers sought to choke off the fuel supply to force Total to guarantee their jobs. The strike at Total, ranked as the sixth biggest oil company in the world by sales, helped drive oil prices above 80 dollars a barrel in New York trading said on February 22.
