The Valmet Automotive plant at Uusikaupunki in south west Finland has started discussions with unions about making some temporary job cuts.
The company is looking to cut the equivalent of 260 man-years, and factory workers, production and support staff could all face being laid off for up to 90 days.
The company says it needs greater flexibility in the workforce through until the start of 2020 when it expects the order books to return to planned levels.
Valmet Automotive has 5,500 employees in Finland, Germany, Poland and Spain, and as one of the biggest employers in the south west, has become a economic success story of Satakunta region.
Valmet inked an important deal in 2017 with German car giant Daimler to start producing a new Mercedez-Benz model at the Uusikaupunki plant.
The company needed to add another thousand workers on top of the people already at the plant, producing two different types of Mercedes.
