Your wrong.The part you're missing is that if the Union and Company can't come to an agreement, the Creditors can then make a proposal that the Judge can use to either accept or not. In that case who wants a completely biased group dictate a contract? Because of the Northwest BK, the Judge will not impose the last offer from the Company, they may impose the original "ask" from the Company which will be much worse than anything negotiated.
I was on the negotiating committee for the mechanic and related at US, we never reached a deal, the judge abrogated and to keep labor peace we voted on the company's final offer, which he could have imposed, he was going to impose it if the vote failed.
I lived it your information is totally incorrect, the company files the motion under Section 1113 to abrogate and impose and the judge has a hearing on it, which I participated and rules on the motion in front of him.
The Creditors Committee has nothing to do with the process, they only approve the total POR which labor concessions are part of.
You really need to go educate yourself, because your posting incorrect information.
