Bob,
It's really simple. The union instituted the ban via the language provided for it in the CBA. By nearly all accounts it's being respected by the membership. You can claim all you want that it's ineffective. The line has been drawn and you chose to cross it. If you're not with us, you're against us. Being in a union means you should take the good with the bad. If we all look out for number one only, it defeats the purpose. I've got the guard to fall back on so I'll fair better than most on the chopping block and much less emotional than most of my fellow Spartans. However, it's still a dick move what you're doing no matter how you try and justify it.
