This article investigates how ‘unaccompanied children’ in Sweden experience one part of the reception system – the social workers – in the context of their everyday life. The aim is to describe and analyse how these young people view and experience social workers and their relation to them, as well as their perceptions regarding the social worker’s nature. The article is drawn from a research project where 20 ‘unaccompanied children’ participated for over two years. During this period, the researchers have met with the young people continuously doing interviews, observations and informal conversations once a month. The results indicate that the social worker tends to become something of a bystander, a representative of the authorities who has played no active role in the young people’s everyday life, except for when they ‘pop up’ to make a decision affecting their everyday life. The social worker becomes a bystander with power. This is discussed in relation to situational ethics and the importance of building relationships and trust to service users in general and to ‘unaccompanied children’ in particular.
