This paper deals with the integration of refugees into Upper Austrian companies from the industry branch. The guiding research question reads: What are the key factors for enabling the operational integration of refugees? With an explorative and qualitative concept in mind, a study of three different cases was carried out. Guided interviews, targeting the groups of the refugees and the human resource managers, were conducted. Two of the three companies were successful with their endeavor, one of them failed, but all of them tried to incorporate the refugees by the means of a “Lehrausbildung”, a form of Austrian apprenticeship. As it turned out, some factors can be seen as important positive effects on the operational integration of refugees: Social contacts to indigenous Austrians offer information and opportunities for jobs, some companies experience a lack of skilled employees and may be more likely to employ refugees, refugees who quickly start to learn the new language are in an advantageous position, and companies who invest into the human capital of their staff are likely to see the integration of refugees work.
