Along with times, changes in values and environment, as well as economic demands led to an increased number of working women. On daily basis, married women work to meet the financial needs of the family. This phenomenon creates a potential conflict between roles at work and in the family, also known as work-family conflict. This phenomenon has many negative impacts, so it's necessary to know the factors that can reduce the level of WFC. Based on previous studies, we assume that spouse social support is an essential factor in reducing WFC. The purpose of this study was to examine the effect of spousal support on WFC on women undergoing dual-career families in Padang. The research was conducted by distributing questionnaires online and offline. To measure the variables, we used the Spouse Support Scale based on the House theory and the Work-Family Conflict Scale based on the Frone, Russell, and Cooper theory. Regression analysis was conducted to see the effect of spouse support on WFC. Based on the results of an analysis conducted on 167 dual-career family women in Padang, we found that spousal support has a significant negative effect on WFC in dual-career family women in Padang. The same thing was also found in every aspect of spousal support with the Instrumental assistance aspect having the largest effective contribution value. It can be concluded that spousal support is a significant factor in reducing the level of WFC in dual-career family women in Padang.
