From what I gathered from the article the freight industry labor force is hyper optimized through PSR. So any time off creates major disruptions to the service and scheduling. There are also monopolistic forces driving control of certain tracks, routes, and stations that make deviating from this system hard. I would think breaking the rail industries monopoly would be a priority to giving the laborers what they want.
