I'll go on board with one case I had a work with a shady female, one where I was directly the victim (two, if you include the shady female) and one where a female coworker sat on info to use for her own benefit.
Get one out of the way first. A female coworker about my age was HUGE into crossfit. She looked amazing and new it, even if she probably would tear every joint and ligament by 50. She was a team lead, so not exactly a worker bee. Our program manager would send her occasional emails saying how "hot" she looked.
Program Manager.
When she showed me these and I asked why she never brought it to HR, she said she was keeping them in her back pocket for whenever she needed something. Now... this is in a Classified environment and we frequently have interns from Mason, 2/3 being female. I thought of them. If this female coworker wanted to sit on the info... fine... but she did so at the loss of the young interns. Every time I'd see the PM sitting down with one of the interns to see what their needs word (so not the job of a PM, by the way), I'd want to walk over and smash him in the face. I can't say anything, though. Not my place.
Another about ten years ago, a black female coworker whose husband was partner in a business law firm in DC was obviously being treated poorly and singled out by a newly-arrived team lead. A brand new position created just to give the guy a job since his program was dying and the new PM was his PM over there. Makes zero sense, I know. After a month or so of this, I led a few others to HR, but wouldn't do it without the backing of my team. They all did. When all was said and done and all the proof, emails and etcetera were given, not a single thing was done to the newly-arrived team lead. Instead, the female coworker we stuck up for, an older coworker and I were put on a separate team... just us... and had the worst hours imaginable. They could say there was no legal vindictiveness, however, because they didn't change our titles and salaries. That's how they protect themselves. The older coworker retired shortly thereafter and the two of us wound up leaving for better programs.
Last... about two years ago I was accused by a female coworker of some very shady things. I was able to go back and prove it was actually her, but the bottom line was my name got thrown in the ringer with our prime on the contract as well as my HR. My boss, a female, knew better. She knew it wasn't me and that the coworker was no only lying, but was the true guilty party. When HR did ask me what I wanted to do, I said nothing. Maybe that was a bad decision, I don't know. Turned out my coworker didn't like being turned down, but all I could think about was her kids going without. I have three of my own and, while I wouldn't do anything stupid, I also wouldn't want to look bad in their eyes and unable to care for them.
I can guarantee we've seen enough of this to know that, even taking into account the biases of the Compost, none of the scenarios I've laid-out is what has happened in Ashburn.
