I have done quite a bit of Worship service and recognize the difficulties discussed here. For me it has always been best to not be a part of leadership, but to remain simply a volunteer willing to serve as needed. If I can be a positive resource able to contribute something, great.
This approach keeps me out of the body politic and the stresses associated with it. Afterall, that is what a Worship Leader is paid for.
I just make sure Leadership knows I am available, humble, flexible, and willing to serve as needed. Then, when called upon, I show up at rehearsal thoroughly prepared.....patches ready, arrangements down, intros, outros, ambient stuff for prayer....that's where I put the effort.
