The aim of this study was to examine how social workers work with school absenteeism. More specifically the aim was to find out when social services got notified about the problem, how the work was structured and how cooperation between different partners worked. To discuss these topics we interviewed seven social workers on their experiences with children with school absenteeism. Five key themes were identified during the interviews. The children come from varying problematic backgrounds, the work was tailored for each individual, the need of identifying the problem in an early stage, the importance of building relations with the child and that cooperation between partners was essential. The work with school absenteeism was considered difficult by the social workers, thus supporting the results of previous research on the topic. In the analysis a conclusion was made that emphasized the need for preventive measures.
