UPMA received the below MOU from USPS Headquarters. Make sure that when you have people questioning how much they can work to make sure that they are following the pecking order and as much as it might cause some extra work, I would strongly recommend that they are documenting that they have followed that pecking order before they exceed the 15 hours of bargaining unit work.
