The French carmaker has announced that it will not replace retiring workers so as to cut its workforce by 15% between now and 2016. The decision has come just six months after a restructuring plan at PSA Peugeot Citroën which involved the loss of 8,000 jobs, and at a time when sales of new French cars have slumped: falling by 19.4% in 2012, the worst decline since 1997.
