The objective of this paper is to develop a cross-cultural aspect management system for Thailand Labors. According to the official statistics, there are over 300,000 foreign labors in Taiwan currently, and Thailand labors are the largest part of them, which counts over 40%. Thus, to develop an effective management system for them becomes an urgent issue at this moment. However, we found the previous studies are mostly focused on developing the system from managers' subjective viewpoint; it is still lack of the study from the aspect of culture differences. In this paper, we use Hofstede's five dimensions instrument to examine the culture differences between Thailand labors and Taiwan labors in Plastic and Fiber Industries. The results of the cross-cultural survey showed that four of five dimensions exist significant different which are power distance, uncertainty avoidance, individualism, and long-term orientation. And the dimension of masculinity is insignificant different. Based on the results stated above, we finally propose a management system that is more effective and feasible to Thailand labors.
