Hmmmm..
In general, the wording seems to favor the debtor company over the employees. At the end of the day all the judgement calls and grey area in 1113 are determined by the courts, and there is no tried and true litmus tests for whats fair in what circumstance. Basically, if I were labor, I would probably chose any other option that would avoid 1113.
Just like any other phucking legal document, lots of holes no clear lines, so lawyers can argue about it for days charging mutliple hours to their clients. Of course while the lawyers are taking all their clients money without providing value.
