Can someone please give me a primary source and a secondary source for women entering the workforce world war II

Primary source: A letter written by a woman who entered the workforce during World War II, describing her experiences and challenges. This could be found in an archive or collection of personal letters from the time period.

Secondary source: A scholarly article or book that analyzes the experiences of women entering the workforce during World War II. One example is the book "Rosie the Riveter: Women Working on the Home Front in World War II" by Penny Colman.
