Social workers in New Zealand other schools work with other school professionals to respond to potential child maltreatment in the school setting, but little is reported about their experience of interprofessional collaboration. An exploratory qualitative study focused on school professionals' process when responding to child maltreatment. The author conducted 20 semi-structured telephone interviews with social workers to explore their interprofessional work with teaching professionals. Many challenges were reported including power imbalances; resource issues, especially inadequate time given their placement in multiple schools; marginalisation, and teachers' inconsistent understanding of the social work role. Social workers reported relationship-based strategies to manage these challenges, and a sense of pride and identity was apparent in these accounts. Patient relationship building was a key strategy to build respect and understanding of social work knowledge and skills. A reading of Bourdieu's discussion of social distinction suggests social work is often perceived as a profession lacking the confidence of the "distinguished possessor" of capital and more of the uncertainty of the "pretentious challenger". A professional capital framework, that positions school-based social workers as 'guests' in a host setting, is useful in understanding these dynamics and how social workers choose to respond. This study suggests that preparation for school social work might usefully focus on interprofessional working and in particular support the development of conscious, principled yet pragmatic relationship-building skills to bridge the gap between the teaching and social work professions and improve the welfare of children.
