The purpose of this study is to examine the longitudinal patterns of change in work-life balance among married women managers. To achieve the goal, the 3rd~6th data of Korean Women Manager Panel (2010~2016) was used. In the case of married women managers who have children, the difference between age groups of work-life balance was examined through a multi-layered growth model for at least two times included in the panel data, and the variables affecting work-life balance changes Was verified. The results of the analysis are as follows. First, the work-life balance of married female managers generally increased over time. However, after controlling individual and organizational variables, the difference in age group changes was significant, and work-life balance was reduced in the 20s. Second, the work-life balance was increasing when there were no preschoolers, but the work-life balance fell when there were no preschoolers. Third, the variables that significantly influence work-life balance were age (generation), presence of preschool children, education, and company size.
The results of this study, in which the changes in work-life balance since 2010 differed from generation to generation, show that the continuously expanding work-life balance system and policy support have not been effectively reflected in married female managers in their 20s and 30s.
