During World War 2, women took on many jobs traditionally done by men such as factory work making bombs, serving as nurses, mechanics, farmers, and engineers. Over 3.5 million children were evacuated from cities and many women helped care for the evacuated children. Women also joined the Women's Land Army and Voluntary Service to help with farming and provide support to firefighters during bombings, though the work was difficult and conditions were poor. After the war, most women lost the jobs they had taken and returned to traditional roles.
