Labor gives their side of the story first and your ba steward and you listen. You should take notes at this time. Then it's your ba's turn to dispute , explain , or plead for your stupidity. If an agreement can be reached ( dead locked) at this local level hearing then great. If not then it goes to a panel or I your local has arbitration the It will go there. Just because it's dead locked any the local level hearing doesn't mean a settlement can't be reached before it goes to the panal.
