Also is it not a good thing that I’m meeting with the center manager the labor board and my BA? It’s not the panel obviously but I never seen anyone else meet with them like this so I’m really worried....
From the perspective of a former management person -
Don't be concerned that you've never seen this type of meeting before. It's part of the process and is supposed to be as discreet as possible. It's most likely happened in you building before and that fact you were not aware of it just means that those involved didn't blab about it. That's an indication they are behaving professionally. That's a good thing.
The union will clearly not push for your termination. The center management team won't either unless you're a horrible driver or you go out of your way to be a phallus to them every chance you get since gaining seniority. The decision to push it to panel will ultimately rest with the labor manager. S/he will most likely follow the center teams recommendations.
Most likely you will get suspension served and a stern go now and sin no more. Don't worry so much.
