The IAM and U mgmt. have an idea of what a worst-case outcome looks like if a judge abrogates the agreement. The IAM's goal at this point is probably to construct an "alternative outcome" that will allow for better wages than what U is proposing or the Judge might order. Could this mean that the IAM is currently working with an alternative suitor to the TPG? Given the union's track record with other airline restructurings, I'd venture to say yes...
