MILAN Unions called for a one-day strike at Stellantis' Melfi plant in southern Italy on Sept. 18 over lack of details by the carmaker about the new models to be produced there, a union representative said on Friday.

Marco Lomio, the local head of UILM metal mechanic union, said UILM, FIM-CISL, Fismic and Uglm unions had called the strike after a meeting on Friday in Melfi over future productions in the facility.

The strike is not related to the ongoing action by United Auto Workers in the U.S. at three factories owned by General Motors, Ford Motor and Chrysler parent Stellantis.

Stellantis was not immediately available for comment.
