It's not unavoidable, a lot of people don't do it. I would say they are making a mistake though.
The thing is that people on the other side should either recognize what you're doing or appreciate you relieving the tension in their internal politics enough that your emotional labor is rewarded with a positive atmosphere.
If that doesn't happen then you can only hope they're paying well. Doing this comes naturally to me though and I struggle in environments where you need to be a self-promoter so maybe it's a "horses for courses" situation.
