 The sense of community that arose from working and living together contributed directly to the energy and growth of the first union of women workers , the Lowell Female Labor Reform Association . Started by twelve operatives in January 1845 , its membership grew to 500 within six months , and continued to expand rapidly . The Association was run completely by the women themselves : they elected their own officers and held their own meetings ; they helped organize the city ’ s female workers , and set up branches in other mill towns . They organized fairs , parties , and social gatherings . Unlike many middle @-@ class women activists , the operatives found considerable support from working @-@ class men who welcomed them into their reform organizations and advocated for their treatment as equals .
