The article elaborates what aspects of knowledge eldercare workers describe concerning everyday long-term care practices. The article utilises a thematic analysis of Finnish long-term care workers’ semi-structured interviews (n = 25), and in doing so, it contributes to the discussion concerning the epistemological basis of care. The analysis specifies four aspects of knowledge in long-term care work: objective/objectifying, particular, corporeal and tacit. In line with existing literature on knowledge and care, the findings indicate that rational-technical epistemological approaches are insufficient when complex and fluid care relations are concerned. Moreover, cognitive impairments and other particularities of eldercare provide previously under-researched epistemological perspectives for consideration.
