The purpose of this study is to identify the types of dual-earner couples’ work arrangements with a focus on the multidimensional characteristics of work time such as work hours, schedules, and flexibility. It also sought to investigate the relationship between the types of work arrangements and work-life balance. Data came from Wave 17 (2014) of the Korean Labor & Income Panel Study (KLIPS). We used the subsample of 1,150 dual-earner couples who worked as paid workers, self-employed workers, or unpaid family workers. Using latent class analysis, the 5-class model was selected: (a) Type 1: couples working full-time with standard schedules; (b) Type 2: husbands working long hours with flexible work schedules and wives working full-time, standard schedules; (c) Type 3: both partners working long hours with flexible work schedules; (d) Type 4: husbands working full-time with standard schedules and wives working full-time with flexible work schedules; and (e) Type 5: husbands working long hours with nonstandard schedules and wives with rigid work schedules. There were differences in the levels of work-life balance depending on the type of work arrangements of the dual-earner couples. Overall, Type 4 couples reported higher levels of work-life balance. By identifying the diverse types of work arrangements among dual-earner couples, the present study suggests that customized family and labor policies are imperative to support dual-earner couples’ work-life balance.
