I spent the day with my boss, wondering if tomorrow I'd be the guy that was next on the "ax" list. I'm not. But I have had weeks of wondering. I'm not out of the woods by any stretch, but I have at least another few months of safety. This is no way to exist though. As per your problem, I feel for you. There really is only one solution for such things and it's communication. Usually, this would entail a third party as witness. Sit down with her and in a calm, thoughtful and genuine way explain how she is making you feel. Let her know that you want nothing more than to work together and ask how you could be a better teammate. -Having a third party there is paramount. DO NOT DO THIS WITHOUT SOMEONE ELSE PRESENT THAT HAS NO "skin" in the game. Better yet someone that outranks you both. Good luck!
