As millions of men were drafted into the military, women flooded the workforce to keep war production running. 'Rosie the Riveter' became the iconic cultural symbol representing the six million women who worked in defense plants and shipyards. These women took on 'men's work,' operating heavy machinery, welding, and building B-29 bombers. This shift was not only vital for winning the war but also fundamentally changed the social landscape, proving that women were capable of high-skill industrial labor and laying the groundwork for the modern women's rights movement.
