I have definitely dealt with difficult people and not only in jobs, but also in the family and I have seen that giving explanations does not help, what they do is to entangle the situation and turn it in their favour.
So those four points are excellent. On the other hand I don't like to argue and it makes no sense with a difficult person. We've all been difficult at times, but some people are difficult all the time. The best thing to do is not to play their game.
I good kick in the head is one way to deal with difficult people...but it's not always possible or prudent, so it makes sense to learn some other ways to deal with them huh?
It's a very good solution .... or a good punch haha I would need a very strong stick! But let's look for something else.
