Up to 6m workers could lose their jobs as the automotive industry continues to fail, the general secretary of the International Metalworkers’ Federation said yesterday. “Worldwide, maybe we will lose something between 20 per cent to 25 per cent of our membership,” Marcello Malentacchi said. Malentacchi said that the car market’s contraction is likely to reach its worst at the end of this year. The recession has so far caused a 16 per cent drop in European car sales this year. Carmakers are responding by slashing manufacturing capacity and jobs.
