The purpose of this study is to explain what workers, who have experienced atypical work, experience in the process of job mobility, job change, or choosing a different worker status than before. The researcher analyzed the interviews with 20 research participants who have had various job experiences according to the grounded theory method. As a result, 432 concepts, 115 subcategories, and 36 categories were derived. The central category derived through the paradigm model and pattern analysis process is ‘Overcoming the barrier to reemployment by helping with work experience to extend the working life’. In the context model analysis, workers were influenced by the working life stage or the workers' turnover environment; and they accepted atypical work non-acceptance, strategic acceptance, or involuntarily. In this process, it was found that workers consistently aimed for job stability. The significance of this study is that it has accumulated data to explain workers' desire to expand the period of participation in economic activities and to explore new directions for active labor market policy.
