This is old news. JH has refused to put a time limit on the wet lease because it lasts for five years and they have no intention of ending it before that. Committing to a dry lease beyond the agreement is irrelevant to this agreement.
The way the union wrote their submission is smart, in that VA should terminate the wet lease at 3 years unless a dry lease is signed and started at the end of the 5 years. But I doubt VA will go for that.
