While Harley's been selling everything they make any money made off the vasaline tax was a dealer issue not a factory issue, so yes they've been making money, but no probably not as much as you'd think.
The contract as presented here is pretty standard anymore, increased contributions and co-pays for medical from the members with increases to retirement and general wage increase and cola's from the company.
My own union, I.U.O.E. had to go through the same song and dance last time our contract came up, all in all it was a fair package but we lost some ground over here and made up some over there. Just the way it is anymore.
A strike authorization doesn't mean anything, that just shows the company the union has the members support going into negotiations, without a strike authorization from the members the union has no teeth at the bargaining table and both sides know it.
