Why did everyone work at the big house in ww1?

During World War I, many people worked at large estates, often referred to as "big houses," due to the labor shortages caused by men enlisting in the military. Women and older individuals took on roles traditionally held by men, managing farms and household duties. Additionally, these estates often had resources and land that were vital for food production and other wartime needs, making their operation essential for supporting the war effort. This shift also contributed to changing social dynamics and the roles of women in society during and after the war.
