A global network of person-to-person contacts between people working as carers, whether paid or unpaid. See Hochschild in W. Hutton, W. and A. Giddens, eds (2000). A common care chain typically entails an older daughter from a poor family who cares for her siblings while her mother works as a nanny caring for the children of a migrating nanny who, in turn, cares for the child of a family in a rich country. Yeates (2004) Feminist Rev. 77, 79 is excellent on this, as is her state-of-the-art review (Yeates (2012) Global Networks 12, 2, 135).
