Resumo Este artigo analisa as experiências de migrantes latino-americanas que trabalham, ou já trabalharam, como domésticas e/ou cuidadoras na Espanha. O texto destaca dois tipos de situações vivenciadas pelas colaboradoras deste estudo, que dizem respeito, em primeiro lugar, à precarização e à desvalorização de seus trabalhos, acarretando exposição a longas jornadas, a baixos salários e, até mesmo, ao não pagamento. Em segundo lugar, situações que se referem às dificuldades, ao assédio e à violência que elas enfrentam em seus ambientes de trabalho. Ambas as situações existem como resultado das desigualdades de gênero, de classe social e de nacionalidade com as quais as migrantes entrevistadas se deparam na Espanha. Nesse sentido, apesar de todas as colaboradoras possuírem a documentação espanhola, elas ainda enfrentam uma segregação laboral que determina que continuem realizando, majoritariamente, os trabalhos de reprodução, sem que haja mobilidade de alcançar outros nichos laborais.
