I don't think there can be a lawsuit. I DO believe that this should be referred to the NMB. The DOL should also now be involved. US has proven that they have an attitude of disdain and disinterest in fufilling their Federally mandated negotiations and agreements. This isn't a lawsuit issue for the Union to take up; it is one that the Government should take upon and the Company should defend as criminals, for that is what they are by breaching legally negotiated agreements.
