The purpose of this research is to examine the factors that influence whether married working women with children feel their work is worth doing. A questionnaire was mailed to women in 5 unions of the Japanese Trade Union Confederations in 2005. About 90 percent of respondents were regular full-time workers. Based on a three step regression analysis, the major findings are asfollows:(1) Positive factors are related to the level of consciousness at the workplace, that is they perceive the possibility of promotion to a higher position, they have good relations with colleagues and supervisors, and they work in a family-friendly environment.(2) A negative factor was that they felt discrimination from men with the same career path.(3) Among working women with children under three years of age, time inflexibility such as overtime work with their coworkers is a greater negative influence compared with mothers having older children.
