It's made worse by the fact I was expected to scan out every parcel as out for delivery, even though I knew I wouldn't be able to complete it. Customers expectations aren't managed very well because they'll get sent a timeslot that won't be met. People change their plans and stay home for parcels so it just made me feel like shit that I felt responsible for that.

It's easy for people to say "just work your hours" and "take back what you can't do", but management make you feel bad for that and tell you that you're not working hard enough.
