Should they pay for the pension and retiree costs of employees they haven’t even hired yet?
Nope. They have enough problems with paying the lavish pensions and benefits for their EXISTING employees. According to the GAO, current wages, pensions, and benefits account for more than 80% of the USPS’s costs. The USPS obviously has a structural problem, blame for which I suspect can be laid entirely at the feet of the Postal union.
