The idea of "giving back" is subjective and so is the perception of risk. Those involved with IBB report that positive progress was made--
on the whole. It's not realistic that the pilots would get
everything their own way in IBB. One has to compromise unless the other side has no interests at all. Knowing that was
not the case, it looks like the final deal was quite fair.
I think the big picture changes frequently so you'd need more than
a glimpse to stay current...

Many just make educated guesses and even those who
are in charge of drawing the big picture have to deal with their own share of uncertainties. After all, the final outcome won't be known until the last ballot has been counted. To my way of thinking, that makes every NJ pilot a part of the picture--a mosaic if you will.
I understand your concern is higher now. Last time the pilots voted there was a common "enemy", but this time the pilots are pitted against each other as different interest groups compete for their ideal of the better contract. A bit unsettling for sure.
As to speculation about behind the door deals, I find the idea of it intriguing and promising. Those following along have heard talk/rumors that some of the NJ pilots
may want to leave Teamsters and that there
could be an integration with NJI sooner, rather than later. I don't see either possibility as a negative event. In trying to connect the dots,
speculated swaps (if true) can help explain much of the IBB proposal, especially the duration. I think it's important not to lose sight of the fact that IF deals were made then that means that both sides had achieved a new level of trust and cooperation not previously obtained. Surely that bodes well for all NJA employees.
I think the NJ pilots should trust their SU leaders (who haven't disappointed them so far) and give positive reinforcement to a process that seeks fair solutions arrived at respectfully and in a reasonable time frame. A vote of confidence now will help to establish a new way of doing business that benefits all involved. In my opinion, by far the greater risk would be in turning your back on those (from both sides) who have gone to considerable effort to increase the job security and bring improvements to the overall pilot group you're a member of. Best of luck with your decision making process, IM.
