The Principle of Rotation
Traditionally, rotation ensures that service positions, like nearly everything else in A.A. are passed around for all to share. Many positions have alternates who can step into the service positions if needed.
To step out of an A.A. office we love can be hard. If we have been doing a good job, if we honestly do not see anyone else around willing, qualified, on with the time to do it, and our friends agree, it's especially tough. But it can be a real step forward in growth.
Among other things, anonymity in the Fellowship means that we forgo personal prestige for any A.A. work we do to help alcoholics. And, in the spirit of Tradition Twelve, it reminds us "to place principles before personalities."
Many outgoing service position holders find it rewarding to take time to share their experience with the incoming person. Rotation helps to bring us spiritual rewards far more enduring that the fame. This happens at all levels of A.A.
