Are you trying to say if Amazon works less hours delivering packages , less packages will be delivered because they are already pushing every productivity edge

Are you trying to say if Amazon works less hours delivering packages , less packages will be delivered because they are already pushing every productivity edge possible? That is shocking to me. It feels like I just push these buttons and the package shows up to my door like magic. I assumed everyone has a job pushing buttons so why would we waste time pushing buttons for more than 4 days a week.
