Like many
Boston Brahmin women, Kehew spent much of her time volunteering. Rather than focusing on charity work, however, she used her social position and political connections on behalf of working class women. Quiet and self-effacing, she preferred to work behind the scenes, lobbying legislators and soliciting donations from her wealthy friends. In 1886, Kehew joined the Women's Educational and Industrial Union (WEIU), a cross-class organization dedicated to improving working conditions for women. She served as WEIU president from 1892 to 1913 and as chairman of its board of government from 1914 to 1918. Under her leadership, the WEIU was transformed from a charity group to one focused on educating and organizing female workers. It provided legal advice, counseling, educational classes, and vocational training. Simmons College took on some of the WEIU's vocational training when it was founded in 1902; Kehew was on the college's first board of trustees. In 1905 she established the WEIU's research department, which conducted statistical studies on the lives of working women. This research was used to support legislative proposals pertaining to moneylending, pensions, sanitation, and the
minimum wage, and eventually led to the creation of the Massachusetts Department of Labor and Industry. In 1894, with
Mary Kenney O'Sullivan, Kehew co-founded the Union for Industrial Progress, an auxiliary of the WEIU focused on trade unionism for women. Between 1896 and 1901, the group organized unions to defend the interests of laundry workers, bookbinders, and workers in the tobacco and garment industries. In 1903 she became the first president of the National Women's Trade Union League, a group that supported the organization of labor unions and strove to eliminate sweatshop conditions for women. She served on several legislative committees, investigating working conditions in Massachusetts, and provided financial and other support for various social reform organizations, including the Milk and Baby Hygiene Association, the Tyler Street Day Nursery, and
Denison House. She was active in the
women's suffrage movement, worked on behalf of the blind, and served on the executive committee of the Massachusetts Child Labor Commission. == Death and memorials ==
