Northwest may suspect there is some disaffection in the ranks (of AMFA),
If he refuses to enjoin (a strike), Northwest will be in federal court trying to find a judge who will. And if he does enjoin a strike, the union would go to court.
A lengthy strike by the pilots ? probably anything over 30 days ? would be a disaster. I don't think the pilots would strike with the intention of putting Northwest out of business. Miscalculation. That's the problem.
