I'm sure you are
If Northern drivers don't agree to DOO then there will have to be a guard.
If Northern drivers do agree to DOO, or they are forced into DOO, then the promised "second person" doesn't have to be able to do anything other than stamp a ticket.
My point was that talk of safety duties is a bit irrelevant. Under DOO they won't have any, and without DOO they'll just have to stay as guards.
Obviously I'd hate to see DOO, but I think it will be imposed (with a few sweeteners to divide the workforce).
I don't see how they can force it through tbh. Attitudes to DO have massively changed since James St. Even trying the tried and tested money probably wouldn't work.
