Sarah Reddish (1850–1928) was a British trade unionist and suffragette, who was active in the cooperative movement. A supporter of women running for local elections as a springboard to gaining national voting rights, she ran for office on the Bolton School Board and was successful in her second attempt in 1899. She also ran for office as a Poor Law Guardian, and was successful, but was defeated in her attempt to become a member of the borough council. As a textile worker, Reddish knew first-hand the conditions and wages women experienced and joined unions, working as a paid organiser to help women improve their situations. She was both a socialist and a radical feminist, urging women's equality in the public sphere.
