I read the woman's article and I guess it hit closer to home for me than some people, because while I'm a white male, I'm married to a black woman who works in I.T.
There are certainly some workplace lessons to be learned from the author's insights, but I'm not sure they're all necessarily the ones she would conclude herself?
For starters? Whether you like it or don't... want to admit it's true or don't ... Geographic location has a lot to do with the workplace environment you can expect and its racial makeup. As she admitted herself, the job she took with Home Depot's corporate offices in the South (Atlanta) was one of the places she felt most "comfortable" among her co-workers. If this was as high of a priority for her as it sounds like it was (to the point of her describing health problems due to stress), I would have advised her never to go to Silicon Valley for work - regardless of the promised pay and benefits.
It sounds like, to an extent, she's upset that she can't "have it all" -- meaning working amongst a large population of blacks (with a nice chunk of them being female as well) who share her values and interests, while still earning "top tier" salaries in her field with the biggest industry "movers and shakers".
I'd counter that we simply don't live in a perfect world, and like everyone else, she has to make some tough choices. As a white male who has always had an interest in technology and computing, I knew it was my career field of choice. At the same time? I grew up in the midwest, and found some of my own values made it difficult for me to do such things as running out to the west coast in the dot-com boom era (even when some of my friends did and a couple wound up millionaires). I chose to stick with doing I.T. for manufacturing firms who couldn't afford to pay me that well, but offered some measure of stability and a concept of "life / work balance" that the big tech places lacked. I had family in the midwest that I didn't want to leave, and good friends that I grew up with as a kid and still hung out with. Considering all of that plus the fact that cost of living and housing was reasonable where I lived, it seemed prudent to stay put.
My wife grew up in Memphis, but I think she always knew that she wanted to get out of that area, in order to find more career success. She wound up in New York for a while, Texas for a while, and now out on the east coast with me. She's definitely not anything close to your stereotypical black woman. (Yes, she listens to alternative and classic rock by choice, and doesn't care for much rap music. She also converted to Judaism, among other things people might find outside the norm.) She never had much interest in playing competitive video games though (well, outside of a bit of Guitar Hero until she got bored with it after playing through several songs). (I, on the other hand, still like playing first person shooters, even though I'm in my early 40's.)
If you're working someplace where it's clear the vast majority enjoys and values things you don't -- guess what? That can happen to ANY of us. I worked in I.T. for union steel shops where everyone's interests included hunting, wrestling, monster trucks and country music. I was the only one who listened to alt. rock instead, and cared about a computer as more than just "a pain in the ass tool management forces us to use". I guess I *could* have tried to go hunting or fishing with the guys or start listening to country to try to make new friends. But I didn't.... I just accepted that we liked different things, and went to work to get work done, period. It's a lot easier to enjoy your free time if you have a paycheck and the bills are all paid.
If you're not willing to do that? That's ok... but you have to do your job search based on what's important, then .... which would be finding like-minded co-workers. I know it exists, but she's right that at least for what she was looking for -- it probably won't be found in the "tech giants" of places like Silicon Valley or the Dallas/Fort Worth, TX area. (As just one example to throw out.... the Emerson corporation, last time I kept up with it, had an I.T. department headed up by a black female, and very aggressively hired minorities at their HQ in St. Louis, Missouri.)
