He is acting like a mobster (and there is a history there), I would be looking into him. And that wouldn't be a threat I share with him, I would want to know if he is dirty. If he is, he would go down.
These dickheads were offered a 50% pay increase and turned it down. Over $50 an hour in pay. If their labor strike shuts down commerce to the country, I believe it is the President's duty to get something done. And in the case of the negotiation, when they have already been offered a 50% pay increase, they are the ones being unreasonable. I would (metaphorically) bury him.
