Today was a day of firsts..... In our PCM we were told that volume was WAYY higher than anticipated,and that we 'probably would not be able to make service on all packages" ( in 28 years i have NEVER heard that!) we had a 9 am start time and were instructed to be back in the building NO later than 1030. when i got in at 1030, i got an OMS message to sheet missed in the center board,and NOT our assigned diad. nearly every driver in the center brought packaages, i have never seen so many missed pieces! I worked as directed,and scanned each package with the Center Diad III board. It was set to the center address,and each package was scanned. all of the drivers arriving in after me did the same and when i punched out i confirmed that did not want to complete EDD work. I have NEVER done this before,what could be the reason?
