According to wikipedia the USPS currently employs 574,000 people.
According to news reports they are planning on eliminating close to 28,000 jobs. That's less than 5%
Not that they will be firing 28,000 people. These eliminations will be accomplished via attrition as employees retire.
Not that the USPS will see an immediate savings due to 5% fewer employees because they will still be paid (pension), they just won't be working anymore.
Still, unlike the federal budget, this action will actually result in a real cut rather than a mere reduction in growth.
So there's something happy to think about.
