Stillalbatross, i think its you who are indeed confused about the purpose of a union. Its seems like the years of inaction by the AOA has accustomed you apathy.
You just dont join one cause its the only thing available. You belong to a union that has shown nothing positive ever since giving up on the 49s. You dutifully pay your dues, yet receive nothing in return.
You say "how does that fit in with negotiating a better contract"? How does the AOA fit in? What improvements to the contract have you seen?
At least the CPU gets things done. Show positive results and returns. If they were companies, which would you rather own stock in? Certainly not the AOgAy.
