USPS,FedEx and UPS Scheme to Survive Shipping Slump - Marketing Shift With more business closing, mail and package delivery services are taking different routes to cut costs. The U.S. Postal Service may make history for the wrong reason, as it contemplates cutting as many as 40,000 workers (out of 685,000). According to the Washington Post, USPS mail volume dropped 11% t in fiscal 2008, which resulted in the service spending $2.3 billion more than it took in. USPS may also offer early retirement packages to workers over the age of 50 with 20 years or more of experience.
