Fiat boss Sergio Marchionne has threatened to move production of future Alfa Romeo, Jeep and Fiat models out of Italy after a dispute with an Italian trade union. 

Metalworkers’ union Fiom won a legal ruling against Fiat, which had refused to allow it to represent factory workers in negotiations for more flexible working conditions. Reports say that Marchionne had been approving new investments as each Italian factory agreed to new working arrangements.

Ultimately, if no deal with the unions is forthcoming, the new Maserati SUV and 2015 Alfa Giulia could be built in the US and the Fiat and Jeep baby SUVs in Serbia.
