I don't believe myself to be a difficult person or an overbearing manager. I certainly have goals that my team needs to accomplish and I work hard to listen to others and objectively hear out their opinions and ideas. I give credit where its due, praise my team members and generally try to be a good boss,leader, motivator, guide, example and team player...
In the past year or so, one of my subordinates has for some reason become very abrasive and difficult. When we are with others, my teammember will be very professional, but one on one will make snarky comments and backhanded insults, or just say things that are outright rude, or sit quietly and then when asked why, will imply that things will be my way because that's the only way.
I have been managing for years and never felt that I had a poor relationship with a teammate. I'm truly disturbed and trying to figure out how to handle it. I've done lots of introspection and I really do not believe I deserve this antagonistic attitude and every time I have tried to make things better, by opening a safe conversation, praising my colleague, etc., things seem to get worse.
Unfortunately, I can't simply fire or transfer this person for many complex reasons, and anyway, I prefer to work it out, and learn from the experience.
What (detailed) advice do the wise manager-readers of HN have for me?
If you didn't asked such a downright questions to a people before, that there is a little advise from me.
1. Asking him describe his behavior, not his personal traits or motives. He could be offended personally if you said something wrong about his traits, and it wouldn't improve the situation. If you need to refer to his possible traits or motives, keep in mind that it is all your hypotheses and they are all wrong, because you couldn't make sense of the situation, i.e. they do not describe a reality.
2. Describe him what you feel. Don't forget to mention your emotions, it helps tremendously. Judging by your text, I suppose that it could be something along the lines: I'm trying to do my job good, to be nice with people, I want a good relationships with others and you personally. I need a good relationships with you, but it seems that I failed with that, I'm disappointed and sad, I couldn't understand what I did wrong.
3. Express your hope to find a good resolution of this situation, and let him talk his mind.
Of course, it should be done in a friendly manner, without threats. If your verbal skills allow you to nicely affirm him that there would be no bad consequences for him in any case, that you seek how you could improve yourself, not to harm him, than you probably should do it.
It doesn't help you to become friends with him, probably, but at very least it could make him conscious about his behavior without offending him futher, and he would change it likely. Hopefully it would be a change for a better. :)
