What do you expect? A UNION by it's very nature is a socialist/leftist entity. If you don't like idea of socialist distribution of wealth then a UNION is probably not the best fit for you (where your pay is contractually mandated by seniority instead of work ethic, skill level, and efficiency). You really think AMFA will be any different? Perhaps it will for a time but the endgame is always the same.
If the contract is being followed you are not being shafted and you are not losing money. You can't lose what is not contractually yours despite how entitled you feel to receive it.
There is NO benefit to American Airlines. NONE.
Who cares if it is the last carrier? It is also one of the last carriers to maintain such a large maintenance presence in the United States. Should they follow the other airlines regarding maintenance? Obviously most members are not upset enough to demand a change in representation.
Your elitism is showing. Can you explain to be why you are not ground crew? You are certainly not air crew.
https://en.wikipedia.org/wiki/Groundcrew
Airline ground crew members include: airframe and powerplant, technicians, avionics technicians, ramp agents, customer service agents, and flight dispatchers. Ground crew members are responsible for clearing the runway and gate area of any debris or garbage, in order to prevent foreign object damage by an object being sucked into an engine. The crew visually inspects the tarmac and removes any items found; this is typically called a "FOD walk" and is done prior to an aircraft's arrival and departure.
Look you have your agenda/goals whatever you want to call it and that's great. I say good look to you. However when you start making posts that it insults and demeans you to be associated with "ground workers" frankly I find that conceited. I find it about as palatable as you would find a flight attendant dismissing you as a "dirty grease monkey" and projecting an attitude that you defile the air with your mere presence.
