Now we are supposed to scan the code on the bag instead of each package. Every day now I have returns because they weren't picked up in the scan. I was told to do it this way because if I scan individually and hold up the line it could be an issue. Today and yesterday I was towards the back and had to wait for people in front of me who were still scanning every one. This is really causing more problems it's not working well at all. Need to be more careful with putting routes together. Nobody likes having a bunch of packages to return. Also need to enforce the bag scan, I don't appreciate getting stuck behind people who decide they will do it the old way. Especially after being told it was not a choice, it's the new rule.
