Feminist scholars have also called for greater clarity about the meaning of care (or sometimes, dependency) work and who it is done by, warning against the conflation of the types of care performed by nurse, nurse-aides, home helps, and family members, and equally against the invisibility of the unpaid care work provided by family members compared to the world of (even relatively low-) paid care work. Noting the gendered nature of much longterm care work, a number of feminist bioethicists (Tong 2009; Lanoix 2013a,b) have been examining the ethics of the national and international arrangements of care for children, elderly and chronically ill people, and the associated development of international migrant care work (Weir 2008; Eckenwiler 2011, 2013).
