USPS Office of Inspector General

Your local station shouldn't have given out their number for the simple reason that stations don't have staff to stand by on phones. Clerks are at the windows, carriers are on the street and if anything happens so are the supervisors. The set of facts, 3 carriers on one section of a route at 7:30 suggest that your station was barely able to staff its routes with ordinary overtime but something happened. Could be illness a vehicle breakdown, a dog attack etc. And when two or three carriers finished their ordinary overtime under penalty overtime conditions flooded your route to finish it as early as possible instead of leaving one carrier to do what he can before the 12 hour limit saw him bring back a portion of that route undelivered to wait for the next day.
