I’m a new driver just finished my packet. I just got back from my shift tonight and realized I may have made a big mistake. There is an apartment complex I deliver to that uses a locker system. I was not able to fit all the packages in these lockers do to higher volume from peak season. Usually when this happens I take them to the office and release them there because they have asked me not to deliver them to the doors of the apartments. I go to the office around 2:30 and have found they closed early for holiday reasons. So I sheeted them as closed. There was one package I could not find that I found later at the end of my route so I went back to see if there was more space in the lockers (there wasn’t) so I sheeted it as closed (this is after 5:30) I talked to another driver and he told me I should have sheeted them as NI1. How big of a deal is this?? I plan on talking to my supervisor first thing in the morning about this. Thanks in advance.
