A picture taken on May 27, 2016 shows the Total refinery of Donges, western France, where unionists workers on strike block the access to an oil depot to protest against the government's planned labour law reforms. The French government's labour market proposals, which are designed to make it easier for companies to hire and fire, have sparked a series of nationwide protests and strikes over the past three months. French unions on May 27 called on workers to "continue and step up their action", as a wave of strikes against a disputed labour law disrupted transport and fuel supplies. / AFP / JEAN-SEBASTIEN EVRARD (Photo credit should read JEAN-SEBASTIEN EVRARD/AFP/Getty Images)
