Workers at Fiat’s Melfi plant, which produces the Fiat Punto car and makes components, have given their final approval to a deal between unions and the carmaker. The approval finally ends a period of month-long period of industrial action that disrupted Fat production across the country.

Last Sunday, unions and Fiat executives struck a deal during late night talks in Rome, sending workers back to production lines, Reuters reported.

A veto from workers could have forced unions to scrap the deal, but Gianni Romaniello, head of union CGIL in the southern Basilicata region, said 75 percent of workers approved it, according to Reuters.
