Ugh...for a book about inclusion, it is not nearly inclusive enough.
Almost everything in the book is about women. The author gave pretty meager lip service to people of color and almost not attention at all to the LGBTQ community.
Zero mention of trans and non-binary people, who experience some of the worst workplace discrimination in the US. Plus with R.G. & G.R. Harris Funeral Homes Inc. v. Equal Employment Opportunity Commission [Aimee Stephens case] being in the news and argued before the US Supreme Court while this was being written...just unforgivably exclusionary on the part of the author, who may very well be a TERF (I see no evidence to the contrary) or just very, very, VERY ignorant about the prejudice faced by transgender people, especially trans women of color.
She talks about gender diversity, but only includes men and women, not people who are non-binary, genderfluid, genderqueer, two-spirit, gender non-conforming, or agender, just to name a few groups left out by her old-fashioned, shitty insistence on binary gender.
Plus she copy-pasted the same terms throughout her book whether they were accurate or nonsensical. Women, POC, WOC, and LGBTQ. Just relentlessly copied and pasted throughout. After a while, it just became numbingly dehumanizing.
In other words, her idea of inclusion is some fake-ass bullshit.
She picked some very readable quotes and cribbed some good ideas, but her work is not enlightening or even completely well-informed. I would only recommend to women with the same background as the author, because the book is strongly centered on that experience.
Overall, skip it. You, the reader, can absolutely do better than this.
Alternative recommendation: The Person You Mean to Be (Dolly Chugh) along with Belonging at Work (Rhodes Perry).
