Someone said :
How do you interact with passive agressive people? A person I am on a committee with is very passive agressive; doesnt like being questioned or anyone ever having a differing opinion. When I question I get rudely dismissed. When I say that I feel I am being rudely dismissed I get accused of bullying. This person always has to have the last word on issues and always has to be right no matter what.
I find that starting by using the "ladder of inference" can be useful, to find out the root motivation. Not assuming that they are just passive-aggressive because of a flaw in their character, but that there is something that they need or want, which they get that way more easily.
Finding ways to give them what they seek in a different way can be useful. But it can be hard to do of course!
Here are some tips which are not too bad, especially when it come to separating the passive from the aggressive: https://www.glassdoor.com/blog/passive-aggressive-coworker/
Sometime the only way is either to beat them at their own game, but that makes you as bad as they are.
Or using the "mental judo", you can make them be more passive-aggressive: by exaggerating the excuses they make, how they are victims, how it is not their fault, how they cannot do anything about it, how it is not easy to remember, how the deadline is not important and we should all ignore it, you can lead to a demonstration by the absurd that even them cannot support.
It can also lead them to want to contradict you further, thus turning 180 degrees to appear to be right! (The classical "reverse psychology")
The risk though is that good passive-aggressive people (like me) see though such manipulations. But then it would mean that you are more likely confronted with a psychopath/sociopath (like me), and not a simple passive-aggressive.
