There isn't much they can do, if people want to fly they will. We have a bunch of greedy SOBs that could care less about anyone but themselves. They will be the first to cross a picket line for sure.
I think we could initially try public ridicule. Let's post the names on the board at AOC, and send out a daily email of anyone that picks up a DP voluntarily. Then it is up to the rest of us to avoid that person like the plague when we are on our free time.
I am on the MD-11, and we have disputed certain two leg international sequences on and off for some time now. In the April bid month, the company has increased this type of flying significantly. It is like saying that the company can offer up this type of flying, even though we know you will dispute it, and the wh0res will keep picking them up anyway. It is a slap in the face to us all, and particularly the SIG.
