Diversity has been recognized as a critical predictor of employee behaviors and outcomes in the U.S. Due to the perceived homogeneity of its population, these concepts are relatively new within Korean culture and the effects of diversity characteristics on organizational behavior have not previously been examined in the Korean workforce. Using both quantitative and qualitative study, this book verified that diversity characteristics had a significant effect on employees' perceptions and behaviors. Therefore, this book, demonstrates that even in a visibly homogenous society, diversity exists and it had a direct effect on employees'' perceptions and behaviors. This findings reflect the strong impact of the cultural imperative on people's perceptions and behaviors. Thus, diversity should be understood within a cultural context, as diversity is defined by the people who live in that society. This book should be valuable and useful to professionals in human resource management in multinational corporations and to anyone interested in diversity and multicultural issues in this world of globalization.
