Well, considering the main business of the postal service is door to door delivery, it seems likely the labor ratio would be much higher.
But the fact is they need to reduce their work force. They entered into agreements they shouldn't have, and they have an obligation to honor those agreements as best they can. There neeRAB to be changes in the way public sector unions negotiate, and there neeRAB to be an out for governments that just can't afford the bills. I would say that all future contracts need to have a way to allow mass layoRAB. The idea of having 220,000 that need to be laid off/fired is absolutely ridiculous. They had to see this coming for several years.
