The Lowell Female Labor Reform Association (LFLRA) was one of the first American labor organizations organized by and for women. The Lowell Female Labor Reform Association was founded in 1844 by the  mill girls  of Lowell, Massachusetts. Sarah Bagley was the first president of the LFLRA.
In response, A Factory Girl published a defense of the mill girls in the December 1840 issue of the Lowell Offering, a journal of articles, fiction, and poetry written by and for the Lowell factory operatives. The author was probably Harriet Jane Farley, a mill girl who eventually became editor of the Lowell Offering.
