The goal here is to see what each of us are willing to support. Secondly, what are you willing to tell your reps you are willing to support.
Finally, the NC tells the company what we want. Talking about it here reveals no secrets. It just lets each of us know what we are willing to support.
Either way, we are going to get the contract we are willing to support/deserve. If you don't set the bar, someone else will. I'll bet they won't set it as high as I would.
