Companies affected by the strike launched by about 3,000 members of the Finnish Union of Salaried Employees (TU) told the Finnish News Agency (STT) that the industrial action would have an impact within just days. Juha Heikinheimo, the head of the cruise and ferries division of Norwegian shipbuilder Aker Yards, said the company's Finnish yards, with a total workforce of about 4,000 people, would grind to a halt in a day or a couple of days. Outokumpu said its stainless steel production would halt very quickly while Rautaruukki, another Finnish steelmaker, assured that it could carry on with production but would have to shut down hot rolling and cutting lines. Boliden said production at its Finnish sites would continue thanks to extraordinary measures.
