Yesterday while doing some unrelated research I found the Lewis Hotel Training Course, circa 1935, in the collections at UNLV. It seems to be a guide to working in hotels that explains the duties and obligations of every position. I’ve scanned in the first few pages of the “chambermaid” volume to give you an idea of what it’s like.
You’ve got to click through twice to see them full-size. Make the effort–the trip back in time is definitely worth it. My favorite part is the bottom of page 2, which warns against allowing chambermaids to go to dance halls, “movies,” and other “places of amusement that may be dangerous for them.” That certainly was an era of different social mores.
