It is back breaking and HOT work. I did it for 10 years and my body is still reminding me. They absolutely deserve more than Joe Blow flipping burgers.
That being said, the quality of hub workers, at least when I was there, has gone WAY down. We used to bust our asses everyday just for bragging rights. It was a pride thing. If you were the slacker on the PD, you were ridiculed. We had no respect for you. Now these guys are touching their phones more than packages and I swear I get a contact high walking behind them coming through the guard shack.
