During my career at Nike I have risen to the highest levels in the organization rubbing shoulders at GLS and CLT meetings over the years. Every year I would be given my team's salary information so that I could review equity issues across job bands and titles, as well as to evaluate my distribution of female and male leaders in U, E, and S band roles. There was an obligation on my part as well as my peers to utilize merit and 2 X's pay to resolve issues. If there is a problem with a lack of representation of female leaders in the company, or salary inequity between men and women in like roles, it stems from the highest levels of the organization - think MP and his ilk.
Second, there has always been a "friend of ..." problem at Nike. If it was not TE, it was TC, or CD, or GaryD. There is a problem of "friends of ES" as well, and you can quickly see the "type" of person that gets promoted with the product and ops teams.
Third, by virtue of the number of men at Nike relative to women, there have been significantly more men passed over for promotions than women because of the favoritism mentioned in point 2. There have also been many more men laid off than women for the same reason. I cannot speak for the women's experience conducting the survey that led to the current purge, but this smells of a top leadership issue rather than a cultural problem that has spread to the V.A.L.U.E. levels in the company. And top leadership does not appear to be going anywhere without a golden handshake. Those let go so far are not decision makers when it comes to these problems.
The higher you get in the organization the more you realize the performance evaluations are performed with less due diligence and care, and scrapped together at the last minute. U, E, and some S band people-leaders tend to be the most caring when completing these reviews. The S and S1 reviews and promotions are mostly a "friends of" experience - regardless of gender.
The final point. This issue has existed for years and will continue to persist forever. You cannot take away the preference people have for who they want in their organization. The salary equity issue is easy to review and correct, if the company desires, but the promotion process will always be "unfair" in the eyes of people getting passed over, and the people getting passed over will be mostly men. If I was a 23 - 50 year old man I would be updating my resume and getting out of Nike as soon as possible because the odds will be stacked against my personal development. If you are a woman, every promotion will be viewed as the company tipping the scale in your favor over a more qualified man to achieve a company target. Either way, this is not a healthy position for the company to find itself in.
