What happens when a strike is called? the Feeder Drivers don't pull loads to the Hubs, so there are no packages for the Preload. The Package Drivers don't come into the building to work. The only boxes to work with is what is caught in the system before it is shutdown. Lots of layoffs from lost volume, the low seniority people are out of a job. nobody wins in a strike. I don't think there will be one next year, neither UPS or the Teamsters can afford it.
