When she was eleven, the family moved again and settled in
Saint-Symphorien-d'Ozon,
Rhône, and she became a silk factory worker. After 1840 it was illegal for French children under the age of 12 to work more than an eight-hour day, but Bouvier worked in one of the many factories that ignored the law and she would work thirteen hours. The wages were poor and she and her mother would go without food. Her mother would blame her for being so lazy that her employers did not pay her more. Bouvier changed employers to get better wages and the family moved several times, with Bouvier specializing in textile work. Bouvier was appointed technical advisor and served as an active delegate to the first International Congress of Workers at the first
International Labour Conference held in
Washington, D.C. in 1919. She was a member of the Women's Employment Committee and participated in various International Congresses of Working Women, including the 1921 congress in
Geneva. From 1919 to 1935, she was a member of the Joint Committee for Unemployment Fund. In April 1922, after 27 years of affiliation, she was forced to leave the union. ==Selected works==
