Unions at carmaker Fiat Chrysler said management had given assurances at a meeting on Friday on jobs and a 5 billion euro ($5.54 billion) investment plan in Italy following the group’s planned merger with French rival PSA . The meeting at Fiat Chrysler’s Mirafiori plant in Turin follows confirmation on Wednesday that the two groups had agreed a binding $50 billion tie-up to create the world’s fourth-largest carmaker. Francesca Re David, leader of the FIOM-CGIL labor group, one of the most important union bodies representing the company’s workers, said before the meeting that “not shutting down plants does not mean guaranteeing job levels”.
