This Masters thesis investigates the actual mobility willingness of the futures dominating work force ‘Generation Y, also known as ‘Millennials, with a focus on international assignments. In particular, the thesis strives to fill the research gap by examining Canadian, Austrian and Taiwanese Millennials willingness to work abroad. These countries were selected because of the authors participation in the Global Business Master program at the Johannes Kepler University (JKU). Furthermore, drawing a comparison between the nationalities enables exploration of cultural differences within Generation Ys willingness to relocate for an international job assignment. In order to examine Millennials willingness to work abroad, a quantitative research method was chosen. In sum, 85 Austrians, 49 Canadians and 48 Taiwanese students took part in the survey, mainly represented by business students. The empirical part of the thesis provided evidence about Generation Ys increased willingness to work abroad and, in particular, to relocate for an international job assignment. The results of the thesis study showed that a high percentage of Generation Y (76%) is willing to work abroad which supported the findings of several studies about Generation Ys mobility willingness. This implies that the growing demand for internationally mobile talent due to increasing international markets can be met by Generation Y. A national comparison between the Austrian, Canadian and Taiwanese Millennials interest in working abroad illustrated that the willingness to work abroad differs between countries. While the Canadian Generation Y showed the highest readiness to relocate for an international assignment followed by the Taiwanese one, Austrias Millennials are significantly less willing to work abroad compared to the other nationalities. The differences in the Millennials interest in working abroad were explained by differing cultural values deriving from the literature. Furthermore, the thesis aimed to investigate the types of assignments and incentives why Millennials are willing to relocate internationally, and their lack of interest to work abroad. The quantitative study also showed that a variety of factors influence Generation Ys willingness to relocate for an international job assignment. A statistically significant impact on Millennials willingness to work abroad was found in culture, Millennials international mindsets, international experience, and their field of studies. Within international experience, the exchange semester, length of the exchange and intensive travelling a statistically significant impact on Generation Ys willingness to work abroad was found.
