Either way, your previous comment that forcing mainline carriers to hire ALPA pilots is "closed shop" is incorrect, even under your spurious definition. No one is being forced to join ALPA, they're just being rewarded for it in ALPA contracts.
No, you don't "have' to be a lawyer to read and interpret contracts, but it helps if you want to interpret them correctly.
And thanks for your "help', but I'm quite well versed in the interpretation and use of the RLA and many labor contracts.
