One of the reasons I quit my first job as a bagger was due to call outs.
One Saturday three of our five closing baggers called out "sick" leaving me and the only other bagger who actually did work.
Saturdays were always the busiest day at the store and two of us had to cover bagging, greeter, gathering carts, mopping the entire floor, emptying all the trash cans, restocking bags, and putting unwanted merchandise back. The managers refused to call any of the other baggers for extra help and then yelled and me and M, the two baggers, for not doing our jobs!
We were so swamped that we had to let some stuff go because we're only two people. I worked Sunday again with one of the people who called out on Saturday... all three of the missing baggers had gone to a party and gotten drunk.
These kids were only 16. Sigh.
