Even though intercultural trainings have been developed in Germany since the 1980s (Erll & Gymnich, 2017, p. 152) and interculturality is a key competence at the present time (Erll & Gymnich, 2017, p. 6), it remains difficult for people from a non-German cultural background to work with German employees in their work environment (Erll & Gymnich, 2017, p. 103). The aim of this thesis is to understand the behaviour of German employees in work environments and to analyse how this behaviour impacts expatriates in positive or negative ways as well as which expectations German and non-German employees have in these contexts. The study is based on a qualitative analyse realised on one hand with two German experts in the professional interculturality and on the other hand with five expat-riates that work with Germans in Germany. The study attempts to make recommenda-tions, to improve, and facilitate the relations in intercultural teams of German and non-German employees.
