My intention with the study was to find examples of how school taught German is applied in the Swedish technological work environment within the field of mechanical engineering within and outside the Swedish boarders. By this I tried to find ways to concretize for my future pupils the need of multilingual knowledge in the life of gainful employment in order to make them understand the importance of it and thereby motivate them to study more then one foreign language during their school years. To be able to find any answers to my questions, interviews with Swedish companies in the technological branch were done. With the interviews as a starting point I have tried to find out which linguistic skills are needed in the use of German and when German is more advantageous than English in the working environment. Further, I found example that showed the use of German in working environment in professional context unconsciously promotes application of cultural and social competence by human interaction.
