What occupations did American women not do during World War 1?

During World War I, American women largely took on roles that supported the war effort, such as nursing, munitions manufacturing, and administrative positions. However, they were largely excluded from combat roles, military leadership positions, and many skilled trades that were traditionally dominated by men. Fields like engineering, heavy machinery operation, and certain scientific research jobs remained predominantly male. Overall, while women made significant strides in the workforce, there were still substantial barriers to their participation in various occupations.
