Volkswagen’s (VOWG_p.DE) labor leader has rejected a push by management for a big rise in productivity at the core autos division and said planned structural changes were causing “unease” among workers, according to an interview published on Monday. A goal from Volkswagen (VW) brand chief executive Herbert Diess to increase productivity by 10 percent this year is “unrealistic” and may result in job cuts among salaried employees, works council chief Bernd Osterloh said in an interview with online platform IG Metall bei Volkswagen.
