BackgroundThe family, as the basic socialization environment, is a complex dynamic system that - as a whole and through its subsystems - is in relationships with other social systems (Bagdy in Family socialization and personality disorders. Nemzeti Tankönyvkiadó, Budapest, 2002; Lakatos et al. in Mentálhigiéné és Pszichoszomatika 21(1):56–85, 2020). The system with which the family system has long-term relationships is the work system/environment. Creating and maintaining a work-life balance has become a central issue in our societies, as they are two of the most organising forces, and reconciling them is a very difficult task due to the demands and expectations coming from both directions, often simultaneously (Makra et al. in Magyar Pszichológiai Szemle 67(3):491–518, 2012). This kind of “double burden” primarily affects women, but their increasing role in the labour market is not necessarily followed by an equal sharing of work within family life (Engler et al. in Work-life balance in women’s careers. In: Tardos K, Paksi V, Fábri Gy (eds) Scientific careers in the early 21st century. Belvedere Meridionale, Szeged, pp 114–126, 2021). We hypothesise that involvement in work negatively correlates with work-life balance, making it more difficult to integrate into the family. It was expected that the relationship between the number of children and mothers’ professional involvement would be negative. A positive correlation was expected between the age of the youngest child and the mothers’ work involvement. On the other hand, a family united by cohesion and resilience leads to higher job satisfaction.MethodsFor the present analysis, we analysed the relationships between work-family conflict and family structure in working mothers with children in a sample of 273 participants. The self-reported questionnaire included demographic data and 2 standard questionnaires: the Work-Family Conflict Questionnaire and the Olson-Family Test (FACES-IV.). The study was conducted in Hungary.ResultsNo significant relationship was found between work involvement and work-family conflict. A negative relationship was observed between work involvement and family involvement. Similiarily, no significant relationship was found between the number of children, the age of the youngest child and work involvement, contrary to expectations. The findings indicate a positive relationship between good family cohesion, flexibility and job satisfaction.ConclusionStriking a work-family balance is a challenging process for families with young children, especially working mothers. A mutually negative relationship between work and family involvement has been shown. The importance of a well-functioning family, with adequate cohesion and flexibility, is reflected in family and job satisfaction. The relationship between work-to-family conflict and job involvement is moderated significantly only when family flexibility is low. The results from the present pilot study indicate important relationships between variables and point to further research directions worth investigating in a larger sample in the future.
