The overtime ban doesn't help the current negotiations, according to the Finnish Forest Industries Federation."The overtime ban is not a solution, and the parties should instead convene to settle matters by negotiation. Pro’s demand for a 3.5 percent pay hike is totally oversized in comparison to the other pay solutions reached this spring,” says Jari Forss, Deputy Director General of the Finnish Forest Industries Federation.In addition, the trade union Pro has issued a strike warning. The strike would affect salaried employees at paper mills belonging to UPM from April 6 to April 20.The Finnish collective labour agreement for salaried paper industry employees covers more than 3,000 people.
