RR has a Steve Jobs type "hero - a$$ho-e" mentality. You are either one of her favorites, or you are a goat who she doesn't give the time of day to. And that status can literally change overnight.
With RR, everything was always about HER, and if you could help HER. If she felt you could help her, then you were a hero. But if you fell out of favor, you were a goat and would stay that way, in that status, until (or IF) there was ever a situation where you could help her again. Then you would be back to HERO status as long as you could help her.
Her biggest issue was that she REFUSED to promote people on her team. She would get them right where she wanted them, helping her, and then she would keep them there as long as they were producing, working hard, and making her look good to Oracle executives. No promotion or reward for your hard work.
Eventually after she was leading the team for about 2-3 years, people started figuring this out and eventually (in the year before the pandemic) started leaving the team, and/or leaving Oracle. The drip started out as gradual, and was delayed by the pandemic as people were worried about their jobs. After folks figured out that it was safe (again) to leave, they started leaving in DROVES in 2021, absolutely decimating RR's team.
After some months, enough of the team's senior brain-trust of worker-bees had left, that RR finally figured out that she was in a major crisis, and the wheels had come off her bus under her very nose. Her team was absolutely dead in the water, and she didn't even realize it before it was too late (mainly because she was so focused on brown-nosing Oracle executives).
It was only a matter of time before the empire she had built totally collapsed and imploded on itself. As soon as her main patron (her manager AK) left, she was pretty much done. It was just a matter of time. Which turned out to be the case.
It will be interesting to see where she lands next, and how she "uses" her way to the top of that organization too. Humble and being a servant leader is not a part of RR's vocabulary. Using and abusing people for her own gain and benefit and to support her own lifestyle very much IS her vocabulary.
