MILAN, March 29 Fiat's CEO Sergio Marchionne is being investigated in Italy over allegations of violation of labour rights in a long-running dispute at a factory near Naples, the automaker said on Friday.
Fiat, Italy's biggest private sector employer, said Marchionne and another group manager were notified by the public prosecutor of Nola of a preliminary investigation on Friday.
Fiat said the prosecutor's move was "the umpteenth expression of an unprecedented judiciary offensive directed by (trade union) FIOM against Fiat, for more than two years".
The dispute stems from a Rome appeals court ruling last October that Fiat must take back 19 laid-off employees who were members of FIOM and had filed a complaint alleging discrimination.
Fiat, which controls U.S. carmaker Chrysler, has denied several times any wrongdoing.
Back in February, Marchionne said the dispute at the factory had been resolved, taking the heat out of the controversial issue in the country's election campaign.
Politicians and labour leaders criticised Fiat ahead of the February vote for trying to lay off the 19 workers at the factory, in a country mired in recession.
