This almost deserves a thread of its own, but is in addition to what's been covered earlier.
Someone was up on the 3rd floor talking with DH about the seniority list. Apparently its not being updated in order to hide the number of crew we have, or don't, have. The seniority number you have just now will be the one you retain. Well, mine has hardly moved in the past 6 months; I'll keep an eye on it and let you know if it changes.
