This paper investigates whether the telework experience and management of work-family boundaries by workers has an effect on the work-family balance in the Corona pandemic. The analysis was divided by gender and presence of children, and the results showed that telework experienced under the Corona pandemic reduced the negative spillover only for men without children under junior high school age. On the other hand, no significant influence of telework was observed in other characteristics. Furthermore, factors affecting the work-family boundary differed for each characteristic (gender, presence of children). The results conclude that the hypothesis wherein work-family boundary management under the Corona pandemic reduces negative spillover is partially supported. Therefore, in order to improve the work-family balance, workers need to optimize time management to perform their work/family roles and make adjustments in the other life domains according to their own characteristics.
