An Overview of Labour in Gaols
In Victorian times all prisoners had to work in the gaols, with the type of work depending on whether a prisoner had been sentenced to hard labour.
The main aim of labour in prisons, especially 'hard labour', was punishment. Much of it had little other purpose. Sometimes 'industrial employment' could be found for inmates and the sale of goods made helped offset the costs of the prison and allowed prisoners to earn small sums to help them on their release. There was also a certain amount of labour in the service of the prison - cooking, cleaning etc.
