This research is a two year case study. Kao-Hsiung Lin-Yuan County was the field site, eight workers and their families were our major subjects. The research goal of this study is to inquire and describe the relationship between the social conditions or structural constraints the workers have experienced and their career strategies. By developing cases and through an analysis of the workers' family and life histories, structural features of career opportunities were identified and described in relation to the petrochemical workers' career coping strategies. The analysis also emphasized on the differences between the local resident petrochemical workers who have richer family heritage and those who do not have. Futhermore, one case of a petrochemical skilled-worker who owns a richer family heritage and who already committed himself in the local political election was developed and described.
