The purpose of this thesis was to achieve a deeper knowledge of the dilemma whichcan arise during a social welfare workers judgement of a reunion according to whatis best for the child in relation to a child’s right to their biological parents. Thisbachelor thesis was based on three research questions: What influences a socialwelfare workers judgement of a reunion according to what is best for the child, aswell as children’s right to their biological parents? How does a social welfare workerperceive its leeway during a judgement concerning reunion family reunion? How doesa social welfare worker perceive their authority to interpret according to their leeway?A qualitative study has been used to gain a deeper knowledge according to a socialwelfare workers experience. A hermeneutic approach has been used to answer thepurpose of our bachelor thesis and has contributed to a wider perspective of our study.The focus was to understand the dilemma through evaluating and interpretation. Sixsocial welfare workers participated in the following vignette survey, which werecomplemented with semi-structured questions. The participants have answeredregarding their experience concerning their leeway and authority to interpret the lawaccording to what is best for the child and their entitlement to their biological parents.This bachelor thesis research results show that social welfare workers did possessleeway which implies empowerment to interpret legislation, concepts and varioussituations. This can be seen as a prerequisite for correct decisions to be made duringdaily work. Although, it can also act as a risk since clients may receive differentconclusions depending on the social welfare worker. Furthermore, a conclusion of thethesis is that different judgements are made, even though the contributed informationwas identical. The explanation to these different assessments may relate to the socialwelfare workers leeway and authority to interpret the law, which makes investigatingchildren’s right to their parents and what is best for them even more complex.
