melangy- thank you. That's the approach that was helping me avoid losing my cool for the past couple of weeks, where I just did my own thing. It's just getting to a point where it is getting old. I definitely want to make sure nothing backfires, and at this point, I believe that I can be diplomatic, yet objective when discussing this to someone higher up.
When I called her bossy, I am not at all being biased gender-wise. Whether female, male, or agender..... this co-worker is bossy no matter how you slice it.

I do know what you mean though. When I address this, I am going to avoid derogatory language like this though.
