So Onetime,
What other mechanism do we have, before the next round of negotiations comes along, to improve your schedule? To improve all our schedules? And I don't mean next week. This is a long range plan to improve all types of pairings for everyone.
Hmmm. You guessed it. There is none.
The DP process is what we have. Not perfect, but that's it. It will wither if we do not support it. Your choice.
