There is no AE's and VD's before MD's or vice versa. No this bucket, then that bucket. They can empty both buckets at the same time, one before the other, half of one, all of the other and then the remaining half of the first. It's completely at their discretion and they use that to manage staffing in all of the categories so they don't run afoul of the contractual staffing requirements. The only thing required is the order of the individual bucket.

Actually.....nope. CR just has to honor seniority among types of awards. AE/VD can be intermixed with MDs but seniority must be honored among the "types" (AE/VD being one type and MD being the other).
