The voluntary turnover behaviors exist for a long time, especially the increasing crew voluntary turnover behaviors in recent years. Due to the important effect upon the future of businesses, it¡¦s necessary to understand the behaviors thoroughly and completely. Previous studies focused on how the voluntary turnover behaviors work. However, employees who play in the formal or informal group perform different crew behaviors. By interviewing nine groups, which left their job in the past two years ever, we try to sketch the outline of the group relationship and the crew voluntary turnover behaviors in the businesses. Finally, we analyze the transcriptions and explore the relevance about the group relationship and the crew voluntary turnover behavior.
