Tell them if they give you the same amount of mail you got during the last count, you can make evaluation.
Say if they add part of another route, that will take longer. (Gee, if you could magically do all this work without it taking more time, couldn't you just stay home and let them mail your checks to you? Then someone could deliver them, and that wouldn't take them any time either!)
It's a weekly evaluation, not a daily one.
They are responsible to manage the amount of mail you get, you are not required to bend time and space.
They are responsible to hire a full compliment of subs.
They are total failures, yet they're whipping you. (That frosts my toasties!!!)
