Larry Pay Gap
I think you'll find that disparities of pay at "the great and benevolent company" (sorry, the brainwashing still hasn't worn off) are across everyone, not just between men and women.
When I worked there, discussing pay and compensation was a disciplinary offence, as written in my contract. People who came in through acquisition were often paid less than the company pay bands, but they were in no rush to make up the difference. This resulted in huge differences in pay between people on exactly the same grade.
It's unfortunate that some of those people were women, but I don't think it's strictly gender related.
