I know a few people who have done the feedback to AAR and received a personal response from him including some actions he's taking. Apparently he wants feedback on the May rosters as he's been told that they are much better! It may change nothing and be a fruitless exercise, but at least he cannot say 'I asked for feedback and heard nothing' - there's no harm in trying. Max hours, rostering, leave, crap bidding system, housing shafting etc etc. What's the worst that can happen by telling him again?
