I am also a white woman over 40 that got RIF'd. However, as I was in sales and didn't make quota (neither did any of the men on my team excluding one guy who had a big renewal come due this year) I don't have a leg to stand on. Never mind that my 20-year Oracle veteran boss changed my territory (to much worse accounts) and doubled my quota after the first 2 months. In speaking with other reps who covered those same accounts, it was clear that my quota was 3-4x what anyone else was expected to do in that territory.
Those are the subtle ways that managers can discriminate against women. Essentially, setting them up for failure by making goals so far out of reach that only factors outside of your control could change the outcome.
Unfortunately, this isn't a problem just at Oracle. It's prevalent throughout the Tech industry for woman outside of traditional women's roles (Marketing, Finance, Admins, etc.) I think part of the issue is that a majority of men don't look at their women counterparts and think less of them. Most men are respectful, friendly and inclusive. They still hold the door open for you and help put your heavy suitcase in the trunk when on travel. These men don't notice the subtle snub of women because they would never do it. They don't pay attention to the fact that your boss tries to discredit all of your thoughts only to prove you right later on. They are immune to the times your boss calls men by their names but lumps all women together as 'girls' like we're mindless, giggling teens.
I hate the whole women's lib thing. I want a guy to hold a door for me and show me respect. I have an Ivy League degree and over 20 years of experience in the industry. Most of my male colleagues treat me well. Except for the ones that don't, the ones who ask me to sleep with them because I'm single or tell me to my face that my opinion doesn't matter because I'm a girl. One of the funny things is that the guys who have treated me the worst are the ones who have since been promoted within Oracle, while most of the 'good guys' I knew have moved to other companies.
