For our band in the States band committees are rather a new idea. When I was in the UK it seemed posts were up once a year at the AGM, but the same people tended to fill the spot year after year. What I'm really getting at is what do most of you think is healthy for the tenure for officers of your band? Should it be revisted every year...as need be? Should a new person get a few years grace period? Any and all comments are appreciated!
