Sorry, just a bunch of excuses.
I have already listed a bunch of ways you can get info from the union boards without needing to be visibly involved on them.
I forgot to mention that you can also text, email, or call any/all of the Eboard directly for info on what you may be interested in (although that does bypass the message boards). Same with the stewards.
If you were truly interested in what's going on, why certain things are being done the way they are, what you can expect going forward, etc... you would go to the source of information (Eboard and stewards and committee members, all of whom can be found on or through the message boards) and the people directly involved (the pilots) rather than coming to an anonymous message board and soliciting uninformed opinions because you're worried there MIGHT BE one or two people out there who would want to talk about your opinions (and theirs) during a flight. Especially considering you can always simply say, "I'd rather not discuss it while on duty. I have more important things to think about right now.". I've NEVER heard of any real problems in the cockpit because of unwanted discussion from any "union enthusiasts".
But what's worse is, we have a HUGE fight with the company that's underway right now. There have been, are, and will be things we'll have to do, both individually and as a group, that will make us uncomfortable. This isn't an organized martial arts sparring match for points, this is a knock-down drag-out anything goes fight for our lives where the winner takes all. And whether you approve of this whole thing or not, you are stuck in it! In reality, there are no sidelines to sit on here. Why? Because the company doesn't keep a list of those who simply don't participate in the union "antics". In their eyes, you're a pilot, and therefore a fair target for their games. So even if your opinions aren't in line with the union group think, you're in the middle of it buddy! And you're worried that a little conversation with a "union enthusiast" will make you uncomfortable?! You may as well quit Netjets now if that's the case, because things are going to get far more uncomfortable for everyone than just a little cockpit conversation.
Good luck with all that. But honestly, now would be a great time to use our message board for the info you want, and even to spark up your own conversations there. Mostly, the discourse has been very civil recently, even when dealing with glaring differences of opinion. If you aren't towing the union line, that's fine, but remember it's going to be the union that pulls your fat out of the fire if you fall victim to the company's games, because as a pilot, the company only views you as an enemy, regardless of your views on the union and our tactics.
