I feel like this book may have been more relevant in the US market and when it came out, it's now alomst 15years old. The sections on how men are driven by a primal fear of not being able to provide seems to me to be more of an issue in the US culture with no real employment protection. It's not something that I feel informs the way that my colleagues work and my husband definitely doesn't feel this (in Germany). Also the parts with flexitime / facetime are slightly outdated especially since the advent of dominant working from home. Also in the German culture both men and woman typically have flexitime as standard, at least in office-type jobs. Lastly the examples seemed to be from high-powered environments and/or in sales environments, where everything always needs to be done ASAP. It made me feel that if peopple had more realistic plans then work life would be more pleasant for everyone!
Some sections felt confusing, e.g. men operate differently at work and woman should learn to take things less perosnally, but later men's egos are very fragile and woman shouldn't be too critical.
Whilst the author claims not to be telling woman to change their behaviour essentially the message that came thorugh was that they do. Also the men were quoted as saying if woman are competent it's enough, but actually it's not, because they should be careful not to ruffle the men's egos and feelings. But they should also not "become" men. SO it feels like actually woman should bring all the advantages that they have as woman to the table, but be careful to package it so that it still fits into the men's worldview which is really quite frustrating.
Lastly I found the larger printed quotes in the text annoying, they were just repeating text that was one sentence before.
