For us the worst jobs in the world are Chimney sweeps, Factory workers, Mudlarks and Mine workers.
People in London used to throw rubbish into the river Thames then the Mudlarks, who were children, took the rubbish and they sold the things and bought food for themselves.
Factories needed lots of coal for their machines so boys and girls worked in very dangerous conditions in coal mines and many children died.
Small boys and girls between 5 and 10 years used to work chimneys and climb them. Often the chimneys were very small so climbing up them was difficult the children had lots of accidents.
