I wasn't trying to turn this into a pilot vs. FA thing. I was trying to say that we are all subject to market forces when it comes to our paychecks. If we ignore the market forces and demand wages at an artificial rate, then our companies fail because they cannot compete in the marketplace. Then, you win higher wages until the day your company closes its door. I know I'm presenting a simplified version and there are some reasons to have the union available to the labor, but the uses usually discussed on here are to hold the company hostage because you believe you're being screwed because your wages do not look the same as the guys at the top of the company.
Pilots and FAs are both a group of workers no different than dispatchers and baggage handlers. Yes, your pay and benefits should differ in each of those groups based on market forces. FAs do not make the same as pilots because the skills and responsibilities are different. FAs don't make the same as baggage handlers for similar reasons.
If you think organizing is going to change that, you are just kidding yourself. You may bully the company into some sort of concession if you strike, but you will lose in the long run. I believe that goes for any group. Detroit priced itself out of the market, and you can see how good that turned out for everybody.
