This article uses the qualitative materials derived from in-depth interviews of 25 unemployed workers located in Kaohsiung and Pingtong areas to deal with the issue of under-employment and re-employment of middle-aged job seekers. It reaches the following five sets of conclusion. First, unemployed workers usually attributed their unemployment to external factors. Second, constrained by age, skill and psychological barriers, unemployed workers found it extremely difficult to return to the labor markets. Third, economic pressure stood out as the critical factor to push the employed workers to take under-paid jobs. Fourth, based on the re-employment experiences, four types of unemployed workers can be found: innovative job-seekers, anachronistic job seekers, hopeless job seekers and exploited-marginalized job seekers.
