The details of the buyout package Ford Motor Co. is offering 75,000 union workers show the vestiges of the United Autoworker Union’s might: The package includes full lifetime retirement benefits for workers 50 or older with 10 years of service and a $100,000 account for retirees to use for the education of their children or spouses.

But the deal also shows what the union has been reduced to: Getting a good deal for its members as they leave their jobs forever.
