I would suggest to stay engaged on this issue, and communicate clearly and directly with your Block Rep.

IMO, if you think that the company will negotiate a new retirement plan for us, that is not completely in the company's favor, well, you haven't learned your lesson. There will be a winner and a loser in this outcome, and the company will not engage unless they have a guaranteed win.

This is a path to get rid of the A plan. Be wary of guys with 20+ YOS saying how this should be considered and how great it might be. This is about a select group (senior-ish to very senior) getting a better B plan, since they've already, or almost, maxed out their A plan benefit. Watch the "Retirment Path Evaluation" video, the verbiage of DB vs DC is already there. Stay engaged and don't let this door be opened, we will not be able to close it once it goes out to a vote.
