Express was paying temp agencies almost twice the pay of a normal employee to toss boxes at the Memp and Indy Hubs. They were flying in immigrants from Somalia and putting them up in hotels during peak. It gets to the point where the place was so understaffed the hub couldn't function effectively. Sorts were going on 3-5 hours longer than usual, pushing full time employees into double time overtime. Things have slowed down a bit now that the covid fearmongering is over but you're generally right. Fedex wants that right amount of employees to keep labor costs to a minimum and profits to a maximum.
