Returning to Chicago, she continued to organize women and successfully lobbied for a state factory law regulating the employment of women and children. After its passage, she became a deputy to Chief Inspector Florence Kelley.

In 1894 Kenney married John O'Sullivan. They lived in Boston, and over the years she wrote articles for the Boston Globe on women, trade unions, and labor issues. She continued to organize women workers with the support of the Women's Educational and Industrial Union and also helped found and served as executive secretary of the Union for Industrial Progress, a group studying factory conditions.
