It's hard to be overly critical but managers really do make a difference some have the means to make things better and others simply go out of their way to make few changes to look good on paper while ruining everyone's life. In my personal experience there was little to no communication between the management team at my particular office. I feel that a lot of problems at my office could have been resolved by the little more attention to detail a little better communication skills and a few of the managers could learn some personal skills like how to deal with other employees and customers
58+ miles on a rural route, over 300 stops, and you have to get it all done and get back to the Post Office by 3:00 PM. Saints forbid you have to deliver mail during a holiday season! Be ready to fail a LOT. Be ready to endure your supervisor breathing down your neck a LOT.
