While actually picking up food is voluntary , the delivering of the cards is not. Those cards are mail bearing postage. Not necessarily in any order of importance but there are some issues with the action of your management. There is the willful and wanton action of delaying the mail. Also, the rural carriers would have entered those cards into the scanner as a boxholder , thus, affecting the coverage factor for that day. Then, there is the issue of carriers coming upon donations on Saturday ( customers aware of food drive even when no card was received ) and the carriers not knowing what to do. Even if a carrier would have volunteered to participate in picking up food, management has already said "no" . Does the carrier(s) leave the food or pick it up ? Make your appropriate union representative aware of what has occurred.
