When I first got hired, I was a package handler. The job is not bad, it is just a massive amount of manual labor. I had gotten plantar fascitis at the age of 17 from the job, so then I moved to DA. DA was not as bad, just extremely boring and dragged on through the day. The job itself is not bad for someone else maybe, but for me I dreaded getting ready to go.
10 minute break a day
Tiring, boring, drags on
