The Parlin Memorial Library recently opened an exhibit of the Domestic Workers Photo Project, a series of photographs of domestic workers taken by Mario Quiroz. The project uses pictures to tell the story of workers who clean houses and care for children and the elderly. Some of the subjects are Everett residents. The project is sponsored by the Brazilian Immigrant Center in Boston. Natalicia Tracy, the center’s director, is a former nanny and a board member of the National Domestic Workers Alliance. “I have spent most of my life taking care of children, supporting the elderly, and cleaning houses,” she said in a prepared statement. “The Domestic Worker Photo Project shows the real women who are doing this work and serves to help raise the public consciousness of the inherent value and dignity of domestic work.” Mayor Carlo DeMaria was among those on hand for an opening of the exhibit and reception held at the library, 410 Broadway. The exhibit will be open until the end of the month.
