I don't remember if the judge can or cannot impose a contract. Last time around they could, but rules may have changed. The important point to me is that you're better off with no/imposed contract as opposed to something you agree to for 6 years. With no contract, I think your ability to seek self help is a lot better than now where the NMB sides with management.
Don't know all the legal ins and outs on this, so I'd like to learn more about it.
