I think all this comes down to the individual. If Delta is going after guys for serving our country, that's their little rough adventure not the union's. What type of discipline could possibly come from this that would not cause Delta to be investigated for impeding service obligations.
We can't even staff now, do you think suspending folks will help or firing won't get the attention of some congressman? I would love to see Delta try to impose their will with that situation. It would be a complete failure.
