First, an Impasse need to be declared. The request hasn't been responded to yet.
IF an Impasse is declared:
Binding-arbitration will be offered...
Then a proffer....
If rejected by either party....
A 30-day cooling off period will start....
At the end of the cooling off period, a strike could begin....
In other words SatPak77, it's gonna be a while, if at all.
