Pros
It's a physically hard job, with a lot of initial information over load (no training makes that far more stressful.) Affordable health insurance coverage. The days for the most part fly by because you work as hard and as fast as you can 100% of the time. The customers are usually very pleasant, and know the companies systems (ex: only having 1 cashier, switching carts, being neat with boxes, buying or bringing their bags, having payments ready before being cashed out) Opportunity to advance is easier in slower volume/smaller staffed stores - however training is sparse or non-existing. It -is- a wonderful job, when under the right leadership, and they reward you financially as you climb the ranks, and are happy to promote within.
Cons
Upper Management is a constant revolving door, it makes the direction in the store, on a day to day basis sometimes impossible. Train, train, train. They need to dedicate time to training. Increase work life balance - I get punished for weeks on the schedule when needing a particular day off - understand that no one can be available 24-7 indefinitely for years without needing days off for doctors, car repairs, etc. Can't remember the last time I didn't work through my lunch break because that's the only way I can get all of my work done when it's just me (shift manager) with 1 cashier.
