According to the USPS' recent proposal, its hard to argue against dropping a day of delivery. How does reducing emissions by 503,000 metric tons sound? Or that eliminating a day's delivery has the same environmental impact as removing 96,000 vehicles from our roads a year! These are just a few ways to show that eliminating one day of delivery is really driven by a desire to save the planet.
The USPS is taking this "green" approach to try to gain support and overcome the powerful unions that are resisting the move to eliminate a delivery day because it will result in the loss of 40,000 jobs. Environment versus jobs? We don't want to be the ones to make that choice.
