from what i understand is ,this is the hill to die on for them. that they will not budge on, to the lengths they want any automation done in the last 6 years removed.
If true, imo, they (union boss) have a political agenda and are using the workers as pawns. The package as described by Merl, if accurate, seems pretty fair. Why else would you insist on a nonstarter like “no automation at all”?
