This work explores everyday face-to-face interactions between expatriate and host national employees in cross-cultural offices of transnational organizations and corporations. Applying the concepts of cosmopolitanism, social capital, and network theory, the book highlights both “closure” and “openness” in interpersonal interactions thus presenting more nuanced ways of understanding employees’ transnational business/social connections. It also offers useful suggestions, such as the importance of developing a sense of respect for each other, for those who work in transnational office environments in both home and host societies. The author based her findings on one year of intensive fieldwork in Indonesia, which provides an intimate look at the transnational relationships between Japanese expatriate employees and Indonesian host national co-workers. Social science and international business scholars will embrace this ethnographic study of the relationships formed by these professional migrations.
