I've worked under both variable RAPs (awarded in theory by seniority on a daily basis) and consistent RAPs awarded with the monthly schedule. I prefer the consistent ones (especially when we had line bidding and there was accountability for who was awarded what RAP per reserve line).
I think the only other area that I like NKs reserve work rules is that our LCR to SCR payout is at your hourly rate and not a flat rate, and we have fewer involuntary conversions....
