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.
But in the end, the results were the same. Those were hard defeats, but the mill girls refused to give up. In the 1840s, they shifted to a different strategy: political action. They organized the Lowell Female Labor Reform Association to press for reducing the workday to 10 hours. Women couldn't vote inMassachusetts or anywhere else in the country, but that didn't stop the mill girls.
