<p>The article analyses the negotiation of the meaning of domestic work in the context of the ‘solidarity households’ which accommodated Ukrainian refugees and became an important part of the Czech Republic’s humanitarian infrastructure. Drawing on qualitative interviews and an analysis of public and social media discourse and selected integration policies, the paper shows how boundaries are being negotiated in a&#xa0;specific context—comprising both social boundaries as well as boundaries between unpaid domestic work and work that actually fulfills the definition of regular (paid) domestic work in the household. To better understand the position of Ukrainian women in the Czech market for domestic work, the paper also examines the pre-war period and analyses the systematic gendering and ethnicisation of such work. Special attention is paid to the moral economies of gratitude associated with domestic work as negotiated by various actors: civil society initiatives, Czech host families, and refugees from Ukraine.</p>
