A reader asked what to do with someone on the board of directors of her company (for which she is an executive director) that hired her just because he thought she would be easier to control than the previous executive director. When she resisted his encroachment into her stewardship, he has become increasingly aggressive and nasty.
She asked for advice, and I feel like my advice on these types of issues is a little different than it has been before, so I thought I would share (my current thoughts in brackets):
Ok, a couple of thoughts. First, I think you're right that you shouldn't get down in the muck with him. It's actually probably what he wants from you -- to have you play by his rules. [This reminds of mixed martial arts, actually, with your opponent always wanting you to play the particular style that he is most comfortable with, and vice versa.]
Second, I think that the best thing you could do along with any actual day to day things that you do or interactions you have with him is to make sure that none of what is happening is interfering with the way you conceive of yourself or define yourself in any way. My therapist would call this taking "identity hits." I'll give you a quick example of what I mean. A lawyer friend was telling me about how her colleague at a very adversarial deposition tried to be friendly with the opposing attorney during a break by asking him if he had any kids. The opposing attorney sneered at him, as if to say -- I know what you're doing, playing this game of let's be friend -- "yeah, I have kids, two of them, and then went back to his phone." Somehow, this objectively small interaction made her colleague feel very small, made him doubt his own self-conception of himself as a "nice guy", and someone who people respect sort of as a matter of course. He should have no access to tinker around with those areas of your identity and self-conception, which is your job to keep them safer and more tucked away than you'd keep your passport. [This is not something that sociopaths have to worry about because they don't really associate with their sense of self in this very personal way that non personality-disordered individuals seem to. But having recently gotten more in touch with my sense of identity, I now understand how debilitating these identity hits can be -- or at the very least, they will distract you and impede your performance in a fight.]
Third, you need to be an immovable force to survive and thrive in this type of caustic situation. [Again, sociopaths naturally do this third thing because they have a big obsessive streak and they are capable of hyperfocus, or in this case a single-minded focus on getting one over on other people. I think this is hugely advantageous for reasons I explain later. The rest of the advice is to non-sociopathic people who might not naturally come by this single-minded focus, particularly not for something as potentially boring and fungible as their job.] A lot of religious people get this immovable force assurance from the sense that they are doing God's will. I think you're religious? Maybe you could contemplate or pray what it is that God would have you do in your particular situations, and then act with the confidence that what you are doing is approved of by God. Addicts in 12 step programs submit to their higher power (often as relayed through their sponsor). But their program requires them to make that choice and accept the consequences willingly and happily, the same way that martyrs are happy to die for their cause. Single-minded focus is a win-win approach because you have (1) the confidence and self-assurance that is usually required of high performance and (2) the spiritual or emotional robustness to weather small setbacks without counterproductive self-doubt. [Of course the risk is that your single-minded focus results in a Gallipoli, so be sure to pick your battles wisely before going all in, but do prepared to commit to all in if you get even a hint of your opponent being willing to do so.] There are other ways you can get to being an unmovable force (an incredible sense of personal integrity is probably the other major one or an overwhelming passion). You need to get to the point where you feel like you're not even choosing these choices so much as you are being swept up in something greater than yourself, otherwise you'll probably get cold feet at some point. [It's like they say about athletes, you have to get into the flow where you're not even thinking about your next move, it's just a natural extension of who you are.] The truth is that the actual decisions to be made are so complicated that you can't rationalize to the right answer, likely, and definitely not under time and stress conditions, and if you try you're just going to spend a ton of emotional energy in expecting things of yourself that you have no right to expect [and no adequate skillset to back up].
