Objectives. The study aims to examine whether working mothers have a higher level of work and/or family conflict than the rest of the population. Material and methods. The sample consisted of 199 participants out of which 67 were working mothers. The used materials include scales measuring the level of conflict between work and family, overall job satisfaction, general health of participants, perceived stress and family satisfaction. In order to verify the hypotheses, the sample was divided into two groups – group A, which was composed of mothers with children under 18 years old, and group B, composed of men, childless women, and women with children over 18 years old. Results. There was no statistically significant difference between the sample collected from Group A (M = 2.66; SD = 0.78) and Group B (M = 2.58; SD = 0.75): t (197) = 0.657; p> 0.05. A Two-way ANOVA analysis was performed to further investigate whether there was any relationship between the level of conflict, gender and the presence of children. The results show that there was no statistically significant difference between the effect of gender and the presence of children on the scale of work-family conflict, p> 0.05. A moderately positive correlation was found, r = 0.413, p <0.000, between the conflict level and a deteriorated general health, and a linear moderately positive correlation, r = 0.332, p <0.000, between the conflict and the stress levels. Conclusions. The development explores options for increasing the balance between the personal and the professional life. Keywords: perceived stress, work-family conflict, Bulgaria.
