Nov 23, 2010. /Lesprom Network/. The Finnish Federation of Professional and Managerial Staff (YTN), which represents the employee side of the dispute, has announced a ten-day strike that will begin on 3 December, the Finnish Forest Industries Federation said in a press release received by Lesprom Network. The forest industry, which exports over 90% of its production, reckons that the strike will not affect its production operations. However, the strike will have an adverse impact on its reputation as a reliable supplier of goods. In 2009, the forest industry employed over 3,500 professional and managerial employees, some 3,000 of whom worked in the paper industry or in forestry.
