So, I am in the final leg of the PhD portion of my MD-PhD training. this means that aside from my required ~12 clinical duty hours/month, 90% of my time is spent doing research in a basic science laboratory. Our team is a little larger than average for a lab, but still only amounts to ~10 people in total. Of these, ~6-7 of us are regularly in the laboratory workspace on a daily basis.
Writing because approximately 9 months ago we had a new PhD (only) student join our lab. Initially, no problems. However, to make a long story short, I failed to appreciate that he is someone with a fairly fragile ego. Early on when we joined, I corrected him (politely, professionally, and in a contextually appropriate way) on a couple statements he made. Suffice to say, he did not exactly appreciate this.
He fairly quickly developed an extremely passive aggressive disposition towards me - grumbling his "good mornings" to me, aggressively seeking out opportunities to correct me (sometimes, in conversations in which he was not involved, and more than once his 'corrections' were embarrassingly wrong), and so forth. It's also clear he talks shit about me behind my back, as a 2nd individual in our lab with whom I have a slightly more functional relationship also turned up her passive aggressive behavior towards me. they are both part of a small 'knitting circle' at work who spend a lot of their time talking and getting coffee while I am working hard to get in and out of the lab as quickly and efficiently as I can every day.
While frustrating and discouraging, I believe the strategy I have adopted is probably the best approach available to me. I don't acknowledge any of the hostility and instead am externally cheerful, engaged, and task-oriented. the only time I ever directly acknowledge his attitude is when we have to work together (fortunately extremely rare). In this context, when he becomes clearly frustrated and uncooperative, I say something to the effect of : "Hey my man, you seem upset. Is there something wrong?" Of course because his problem is with me and nothing concrete, he demurs and grumbles a non answer, to which I say "Oh, OK." and I drop it. In doing so, I try to send the message that if you won't engage with me directly, then you don't engage with me at all.
that said, this is somewhat challenging to me, as my communication style is.... extremely direct. However, I know confronting him on his behavior will almost certainly be unproductive, as fundamentally we have no concrete issues - just a clash of personalities. I also know that reacting to him with anger is 1. unprofessional and 2. counterproductive, as it only reaffirms his vision of me as a villain - the foil to his martyr-like 'nice guy' self-image. I also know that fundamentally his issue is that I am a very confident person and he finds my external signs of success (especially my status as MD-PhD student) a threat to his very low self-esteem, and there is no conversation we could possibly have that will change this.
Anyway, curious to hear the collective experience with passive aggressive personalities in the workplace: what works, what doesn't, etc. I am pretty satisfied with my external response to this situation, but I will admit that internally I struggle with the negative emotions this dynamic produces. Any thoughts there would likewise be appreciated.
