During the 1980s, Oliveira joined the trade unionist movement in order to advocate for the rights of domestic workers. She called for better working conditions, especially for black workers. In 2003, Oliveira was elected president of the National Federation of Domestic Workers (, Fenatrad), advocating for domestic workers nationally and internationally. She remained in post until 2017. She was involved in the enactment of laws that protected the rights of domestic workers, including a constitutional amendment that granted greater rights, no. 72, which granted minimum wage, bonus, weekly rest, paid holidays, maternity leave, retirement, and access to social security. Oliveira campaigned for the Quota Law (2012), which allowed the children of domestic workers, as well as indigenous and black people, to enter university. In June 2011, Oliveira was part of the Brazilian delegation to the General Conference of the
International Labour Organisation in
Geneva,
Switzerland, where she participated in the drafting of the
Convention on Domestic Workers. In 2008 and 2012, she was elected to Salvador's city council as a member of the
Workers' Party. == Recognition ==
