I don't disagree with you that unions often try to polarize pilot groups to achieve unity and positive results, but to promise an extreme result with little chance of success is a questionable tactic. SC and SWAPA got the short-term excitement and support they wanted, but now they face the long-term task of pacifying a pilot group that wants to know why SWAPA is not able to deliver on the promises. That's why the SWA pilots' message board went crazy when the proposed SLI came out and was only a partial-staple. I don't accuse SWAPA of doing anything unethical by pursuing a staple, but I wonder how they will proceed from here without further angering the radicals in their own pilot group.
The conclusion you are attempting to formulate and extrapolate is unethical.
