I am a new faculty and I have serious conflicts with my chair because she has taken two of my grant proposals (putting herself as the PI) and a conference research proposal and tools I developed for my study (she put a senior faculty and herself as the first and the second author before me).
There is another new assistant professor in my department: she is American, but originally from a country in the Middle East. She comes to my office for a closed-door conversation once a week before meeting with the chair. Then she asks a list of questions regarding my situation and about other colleagues. Also, she asks me when I am going to leave this position.
At the beginning, I thought that she was my friend, as she seemed she cared about me. However, I realized that she reported my words to the chair because, for example, the chair brought to me what I said only to her as an issue and I heard what she said to the chair—it was what she asked to me—when I walked near the chair's office.
So I began to ignore her and phone calls. Also I do not smile when she comes to my office anymore. Also I told her indirectly "stop". However, even still today she came to my office again and kept asking questions again.
How can I make her stop doing that, smoothly and without any conflicts?
