People seemed interested in discussing the issue of how to deal with "bad chemistry" ( 😀 ) in the lab. I thought it would be a good idea to start a thread about this topic. So far I think we can all agree that bursting into tears is probably NOT the best solution. 😉 Anyone have any thoughts, stories, suggestions, etc. on dealing with a PI, post doc, fellow student, etc. that you just can't get along with? When is it time to dig in and work harder, and when is it time to move on?
In my experience, communication is absolutely key. In the beginning, you do not want to shut the person out. Try to confront each other and work out your differences - don't silently brood about the other person. If you stop talking to each other, things will likely build to a point where one of you will have an outburst (yep maybe even tears).
Every problem that I have had with a PI, post doc, or fellow student can be traced to a lack of communication about problems early and often. If the person is higher up than you, ask them what their expectations are of you and try to see things from their side, and do this early before things spin out of control. It's hard to live up to expectations if you don't know exactly what they are, and the expectations are probably more reasonable than you think.
When you do meet with a higher-up to voice your concerns or problems, one of your greatest assets will be to remain calm, cool, and controlled. Once you bring emotions, ie tears, angry phrases, etc. into the mix, you'll start to come off as unreasonable. In fact, if your higher-up is the one who becomes emotional, your calm words will carry more weight in the discussion. Always use sentences that use personal pronouns - "I" - rather than "you". Say what you feel and what you think, and at all costs avoid directly or indirectly verbalizing your assumptions about what your PI/postdoc is feeling and thinking. This is a sure way to make the person angry and get them to write you off.
This also goes with problems with fellow students. Try to work it out directly with the student, without getting a higher-up involved. If this doesn't work, try to setup a meeting with a third party, such as your PI, where you can discuss the issues. There's a little more leeway here since if things are absolutely impossible to work out, you might be able to minimize contact with the person.
If, after trying acknowledging your differences you still can't get along or fix the problem (give it some time first after your discussions!), I'd say it's time to move on.
