This dissertation increases our insight into the role of the service employee’s intercultural competences in the service to culturally diverse customers. Investigating the effect of the intercultural competences of service employees is of major importance because, as a consequence of globalization, the number of intercultural service encounters has increased dramatically and still does. The delivery of service to a culturally diverse customer-base requires a combination of knowledge, skills and attitude; the intercultural competences (also known as Global Mindset). In this study the hotel sector has been investigated specifically. The hotel sector is an important economic player that continues to grow inspite of economic downturn. The special characteristics of hotel services make the sector also very suitable for the research of face-to-face encounters in an international context. In this dissertation, a holistic approach has been chosen, meaning that in the four empirical studies not only the perspective of the manager, but also that of the employee and the customer was investigated. All three of the above-mentioned are actors in intercultural service according to the argumentation of the ‘service-profit chain’ (Heskett, Jones, et al., 1994). Together, the manager, employee and the customer form the so-called ‘service triangle’ (Bitner, 1990).
