Stocking groceries and large retail stores overnight is an absolutely thankless job. Brutal hours moving high volumes of product with the brute force of lifting heavy boxes to the precise detail of facing items on the shelf.
These types of jobs normally have carefully monitored breaks. With minimal downtime for all the work and movement, you’re doing.
Getting grief on top of all of this for a mistake that you didn’t even make is enough to send you off the deep end.
There’s nothing like watching the sun rise as you’re getting off shift.
