Yes. Agreed.
Both sides agree a parcel is anything with a barcode.
They are having a problem coming up with a definition of unscannable because neither party has had the ability be a Carrier trying to figure this out for themselves on the fly.
I am comfortable understanding that my time spent performing a task needs to be credited.
So for hat it's worth, this is how I have defined unscannable for myself.
1.Whether I have to sort the item into a spr tray or place it in cargo.....could be a variable amount of reasons why. Dont try and define these reasons because you will limit and do harm to the Carrier if you try. Leave this for local management and Carriers to define.
Let local grievances get filed. Wouldn't the defense in support of an unscannable come back to, was the action to handle an item as an unscannable parcel necessary? This process begins in the office.
2. If I receive the item in my parcel tub or pumpkin.
Nothing else needs put on paper at this point in time.
JUST to point out. A Carrier in my office has schools that have huge country mailboxes. She bundles the hold mail and carries it separate (not sure if tub or spr tray) She can fit two days of mail in the mailbox. She was doing unscannable to box. So now with the LOU instead of just delivering it into the box and getting credit for the unscannable to the box she should walk in and get door credit

It's just stupid that to get full credit for her efforts in office she needs to do more work on the street. And then ultimately receive more credit than she would have if this would have just never come up.
We Carriers aren't the ones that chose to put the office time credit in with the delivery scan credit. We also shouldn't be the ones sacrificing our credits because the system that was put in place isn't a fair assessment of time spent.
