Question:  “I recently learned that my manager may be planning to replace me. I work for an art museum and am very active in my professional association.  A fellow member called to inquire about an opening here after he saw an ad on the association website. I told him that I wasn’t aware of any vacancies, but when I looked up the ad, I essentially found my own job description under a different title. The address for responding is our museum. Although no one has mentioned any problems with my performance, I am apparently in danger of being fired. I can’t believe my boss thought I wouldn’t find out about this. Should I talk to him? Or should I just apply for my own job?  —Betrayed
