In 1943 a Guide to Hiring Women written by male supervisors during World War II made the following observations:

* Pick young married women. They usually have more of a sense of responsibility than their unmarried sisters, they are less likely to be flirtatious, they need the work or they would not be doing it. They still have the pep and interest to work hard and to deal with the public efficiently.

* When you have to use older women, try to get ones who have worked outside the home at some time in their lives. Older women who have never contacted the public have a hard time adapting themselves and are inclined to be cantankerous and fussy. It is always well to impress upon older women the importance of friendliness and courtesy.

* Give every girl an adequate number of rest periods during the day. You have to make some allowances for feminine psychology. A girl has more confidence and is more efficient if she can keep her hair tidied, apply fresh lipstick and wash her hands several times a day.
