In my center it is done by sorting truck for at least an hour in the AM. Then skip lunch, just put it in the board. There is the two hours right there!!
They indirect nothing. Ni1 any package you couldn't find at delivery point when found later in the day. Spend zero time looking for the odd numbered house and sheet as NSN. Go into pickup's early and ask if they are ready. Have the DVIR filled and signed, both pages, in the AM. Cheat a few air stops where you know that the customer isn't home anyway. Sign for signature required packages because customer signed info notice or left a note or you have an understanding with the customer. Run off stops rather then walking at brisk pace. Not filing out info notice, just scan and throw away. Throwing heavy packages on shoulder rather then using equipment or power zone. Scan packages for an entire street at 1st stop for that street and leave the other packages in cab. I could go on and on.
Anyone of these could get drivers fired, hurt or at the least progressive discipline. However, UPS will look the other way.......until there is a corporate issue.
