Question: A co-worker told me that he brings a voice recorder to work to catch people talking behind his back. He will tape it underneath a desk or hide it behind a picture. We used to be friends, but I now seem to be on the list of people that he hates. I’ve started searching my work area every morning to be sure his recorder isn’t there. Although this guy’s weird behavior makes me sick, I’m not sure what to do about it. Should I bring this to the attention of human resources? —Nervous in Indiana
