The 2005 list of the Best Companies to Work for in Finland was produced by the Great Place to Work® Institute Finland and published by Kauppalehti Optio in February 2005. The list consists of three lists: general, large organisations' (500 or more employees) and public and non-profit organisations' lists. Three top companies on the general list were also the best of all lists. Our sponsor TELA announced a special award for workplace promoting long career for Hämeenlinnan Seudun Osuuspankki.
