The Washington Post today provides an update on the U.S. Postal Service, and explores its notorious customer service problems:

(V.P. of government relations Tom) Day said that in such circumstances (where long customer lines exist), the branch manager should be out in the lobby, sorting customers’ needs in line and helping where possible. On the other hand, managers inclined to do this are somewhat limited in how they can pitch in because, under union rules, they cannot open an empty clerk station and start serving customers.

No wonder why Wal-Mart is fighting unionization tooth-and-nail.
