time with the WTUL came to an end in 1912 during the Lawrence Textile Strike. Initially the WTUL was able to offer support, opening a relief station providing strikers with survival goods, O'Sullivan was made the operator. However the AFL was opposed to the strike. The Industrial Workers of the World (IWW), a rival union organization which held opposing viewpoints, supported the strike. The AFL demanded that organizations under its control, which included WTUL withdraw any support. While WTUL did comply, O'Sullivan did not and stayed on with IWW. This gained her the "ire" of AFL and unfortunately the AFL also reprimanded WTUL. The relationship between both organizations was considerably rocky from this point forward. O'Sullivan disagreed with the IWW's politics but saw merit in their organizing tactics. She was also very supportive of their inclusiveness policy. She thought that IWW's policy of including diverse ethnic and craft divisions would "lead to that 'spirit of confidence'". She played a key role in meeting with strikers and the strike committee. She even played negotiator with William Wood who was chairman of American Woolen Company. Ultimately the strike would end in favor of the workers. Later years After O'Sullivan finished her relief work with the Lawrence Strike she went on to get legislation passed that would improve the conditions in Massachusetts's factories. She was hired in 1914 by the state as the inspector for the Massachusetts Board of Labor and Industries, a position which gave her the power to enforce the laws she helped pass. She held that position until she retired from labor organizing in 1934. During her years as an inspector she participated in many speaking events. In 1926 she was a delegate to the Women's Peace Conference, and spoke often at Boston's Ford Hall Forum. O'Sullivan died at 79 years old in 1943 at her home in Medford, Massachusetts. Tribute In 1999 a series of six tall marble panels with a bronze bust in each was added to the Massachusetts State House; the busts are of O'Sullivan, Florence Luscomb, Dorothea Dix, Josephine St. Pierre Ruffin, Sarah Parker Remond, and Lucy Stone. As well, two quotations from each of those women (including O'Sullivan) are etched on their own marble panel, and the wall behind all the panels has wallpaper made of six government documents repeated over and over, with each document being related to a cause of one or more
