Rosie the Riveter is an allegorical cultural icon of World War II, representing the women who worked in factories and shipyards during World War II, many of whom produced munitions and war supplies. These women sometimes took entirely new jobs replacing the male workers who joined the military. Rosie the Riveter is used as a symbol of American feminism and women's economic advantage.
"Rosie the Riveter" inspired a social movement that increased the number of working American women from 12 million to 20 million by 1944, a 57% increase from 1940.
Although the image of "Rosie the Riveter" reflected the industrial work of welders and riveters during World War II, the majority of working women filled non-factory positions in every sector of the economy. What unified the experiences of these women was that they proved to themselves (and the country) that they could do a "man's job" and could do it well.
Women quickly responded to Rosie the Riveter, who convinced them that they had a patriotic duty to enter the workforce. Some claim that she forever opened the work force for women, but others dispute that point, noting that many women were discharged after the war and their jobs were given to returning servicemen. For some, World War II represented a major turning point for women as they eagerly supported the war effort, but other historians emphasize that the changes were temporary and that immediately after the war was over, women were expected to return to traditional roles of wives and mothers. A third group has emphasized how the long-range significance of the changes brought about by the war provided the foundation for the contemporary woman's movement. Leila J. Rupp in her study of World War II wrote "For the first time, the working woman dominated the public image. Women were riveting housewives in slacks, not mother, domestic beings, or civilizers.”
After the war, as the nation shifted to a time of peace, women were quickly laid off from their factory jobs. The "Rosies" and the generations that followed them knew that working in the factories was in fact a possibility for women, even though they did not reenter the job market in such large proportions again until the 1970s.
