When I started dating my (now) wife, she didn't negotiate her salary, and was at a company where other people did. I helped her figure out what to ask for, how to negotiate, and how to feel good about it. We built a spreadsheet to arm her with some data (e.g. salary compared to inflation). It worked.
I hope by mentioning it that other people might do similarly.
