Rautaruukki Oyj said ongoing strike action by around 200 workers at its Raahe steel plant is disrupting hot-rolling production at the site.
Sakari Kallo, Rautaruukki production manager, told Thomson Financial News that the company has been informed that staff will return to their posts on Friday morning.
Around 800 people at Raahe had staged a 24-hour strike earlier this week in a dispute over pay. Raahe Works in all employs around 2,100 people.
The company said it plans to publish details of the financial impact of the action later.
