FINLAND — Finland’s three biggest forestry sector companies — UPM, Stora Enso and the Metsä Group — have all announced plans to temporarily close some of their pulp or paper mills due to a two-week walkout by workers that began on Monday. The political strikes reflect worker unions’ continued opposition to the government’s planned changes to labour market legislation. A statement released by UPM revealed that the company planned to shut at least four factories while the political strike is ongoing, and may close more. …Metsä Group also announced that it will close its pulp mill in Lappeenranta, but still plans to continue paying wages for the time being. Stora Enso said its packaging board mill in Varkaus will cease operations from Wednesday. …Petri Vanhala, chair of the Paperworkers’ Union, criticised the decision by employers to suspend wage payments due to the closures.
