Considering that the entire issue at stake here is that old jobs are becoming obsolete due to technology, and new jobs are becoming possible due to technology. The union has NO objection to this. The union STRONGLY objects to the notion that these new jobs are to be non-union. This really doesn't strike me as being all that unreasonable of a demand by the union.
So you're justifying the union thugs slowing things down by 60%, knowing that (a) they'll be paid 100% of their salary and (b) the dock owners can't do ANYTHING about it?
