Add the US Postal Service to the growing list of victims of the recession. The USPS—facing declining mail volume, cash-flow problems, and a growing deficit—may drop a day of delivery. (Guess the next postal rate increase, scheduled for May, won’t be enough.) “If current trends continue, we could experience a net loss of $6 billion or more this fiscal year,” Postmaster General John Potter testified before a Senate committee. The USPS could bridge its budget gap, he said, “by suspending delivery on the lightest volume days”—Tuesday or Saturday. Congress mandated the six-day schedule in 1983.
