In literature, work-family relationships and their related roles and boundarys are usually argued in relation to mother and father who work outside of the home and for whom work and family are two different spheres with diverse identities and roles. The usual division of work and family roles of fathers and mothers is different in the case of foster carers. Foster care goes beyond the boundaries of work and family. Work of care takes place within the privacy of the family home, and their work and family roles are not separated and their bounderies are not so clearly defined. The new Foster Care Act also contributes to the vagueness of relationship between work and family roles. Thus, both roles, each with their own unique values and norms, shape a contemporary understanding of the foster carers' role. To answer the question „How is it when a family becomes work?“, a qualitative survey was conducted. For the collection of dana a semi-structured interwiev, in which 8 female foster carers participated, was used. Previous researches has shown that foster care is gender-based, i.e., majority of care is provided by women, therefore understanding of woman's perspective is essential. The results of this study showed that female foste carers are dealing with the dual role problem themselves and do not identify with only one role but show aspects of both roles in fulfilling everyday obligations, responsibilities and goals. Because of this, there is often a struggle between roles since the fundamental values and norms of work and parent roles are in contradictory, i.e., it often results in so-called fight between „head“ and „heart“. It can generally be said that female foster carers understand and perceive their foster care identity as a „foster-carer“ but see their own role as a „mother“.
