Care work provided in homes and institutions is a public good that is under-valued by society. Care workers are more likely to have low earnings and precarious working conditions. About 9 in 10 care workers are women. Most unpaid care work within households is carried out by women. The 'unpaid care penalty' for women in the EU, which is equivalent to the earnings they lost because of this unbalanced distribution of care responsibilities, is estimated to reach €242 billion per year. EU action in the care sector has the potential for high returns for society. Fostering the 'equal earner – equal carer model' could generate benefits of between €24 billion and €48 billion a year.
