At the start of the war, because of the decline of consumer industries, the number of female workers actually decreased. Also, less incentive to work as families of conscripted soldiers received benefits.
'Total War' called for an increase in the conscription of female workers. But, Hitler wanted to retain the domestic roles of women to maintain civilian morale.
1943: conscription to work for women aged 17-45 (many exemptions, limiting impact).
Nazis caught in the contradictions of their own ideology of female work.
By 1945, women made up 60% of workforce.
