Doherty published "The Poor Man's Advocate" and within this told the story of Robert Blincoe, a former child labourer. This led Doherty to turn his interest to the working conditions of women and children, particularly the exceptionally long days many were expected to work. Doherty set about campaigning for a reduction of working hours to no more than ten per day, known as the Ten Hours Bill. Parliament finally agreed to these requests as part of the 1847 Factory Acts and Doherty's relentless work had paid off.
