This study was conducted to examine the realistic problems of flexible work arrangements, which was a representative policy for work-family balance, based on a review of its effect and influence on double-income couples who were actual users of the system. In this study, an in-depth interview with three double-income couples, totaling 6 parents, with preschool children was conducted on the experience of their flexible work arrangements, and the purposes of the study were to figure out their experienced positive effectiveness and the problems with the difficulty of using the system and to look for their solutions. For the data analysis of the study, it was organized into three high categories and nine low ones by reviewing the entire data on the basis of the frame structured in the derived data through the interview and categorizing the subjects by area. The derived analysis results were changes in households, social and cultural perspectives, and demand for policy and social economic changes. This study is significant in the sense that the perspectives and voice of the actual users of flexible work arrangements have been reflected in the study, and in the future, we expect that it will provide justification and persuasive power for the improvement of flexible work arrangements and serve as basic data for establishing policy directions and support.
