The aim of this study was to investigate the association between working environments and parenting burden in women workers. Methods: A total of 1,033 married women were selected from the database of the 7th Korean Longitudinal Survey of Women and Family (KLoWF). Parenting burden and working environments were calculated based on responses of the KLoWF. Univariate and multivariate analyses ware performed to assess the crude and adjusted associations using PASW 18.0. Results: There was an independently positive association between excessive working (b = 0.37, p < 0.001), irregular working (b = 0.17, p < 0.001), temporal oppression on workload (b = 0.08, p = 0.011) and parenting burden in women workers after adjusting for socio-demographics. Conclusions: This study suggests that working environments are important factors for parenting burden in women workers. The findings of this study will be helpful to policy makers to design plans to decrease the parenting burden in women workers.
