Margaret, her two sisters, Anna and Mary Bateson, and their mother Anna Aitkin were involved with the Women's suffrage movement. Margaret was interested in journalism which she began pursuing in 1886. She then began working for 'queen' magazine where she stayed for the majority of her career. In 1888, she organized a campaign of meetings for the Women's Suffrage Society and on 1895 she published 'Professional Women upon their Professions'.

In 1912, as a member of the National Union of women's suffrage Societies, she wrote a letter to Maud Arncliffe Sennett stating that both men and women should have the opportunity to live in better conditions than they did. In 1920, she was a member of the standing committee of the Cambridge Branch of the National Union of Societies for Equal Citizenship still in hopes of political equality.
