If you "let em work it," then they could end up bankrupting the union and ending all union protection for ALPA members. When you sue your union, you're really suing your fellow pilots.
We're talking about TWA. If ALPA goes BK because it is proven that they witheld enthusiasm for the betterment of TWA pilots' careers (in the least bit), that will be OK. Because in that case, you and I never had any "union protection" in the first place.
Let them work this out and we'll ALL be better for it. Suing ALPA is tough love that they desparately need.
