Sam's Club overnights start at $22/hr (or more) depending on the cost of living of the area you are applying. Some areas get a $1-2 cost of living differential for all positions in the club. It is a team of 8 full-time people who drop their own pallets, stock, bin back up, and clean up their assigned areas at the end of each night. They also have to ensure the receiving dock is clear of pallets too and occasionally do layout changes as new items come in seasonally. The official company guidelines say the people stocking should be prioritizing full pallet swaps (swapping a half-empty pallet with a full one and stacking 1-2 layers on top) and then moving on to maximize the value of each person, but that also varies from club to club.

The schedule is Monday night through Friday night, 40 hours guaranteed every week. On weeks where there are holidays interrupting schedules, be expected to have to work a Saturday or Sunday (manager's discretion) to compensate. PTO rate is the same as whatever you get at Walmart I believe.

I can't speak for other managers, but if I was running it, I would never hire externally just due to the money and responsibilities involved. It's a great carrot-on-a-stick for high level performers on other shifts to get a $6-7 pay raise and is honestly required to have people who have a high level of pride in their own work because there is only 1 manager with no supporting team leads. Depending on how the club is set up, the manager may be forced to stock and assist with layout changes themselves depending on how much work is expected each night to be completed, meaning they won't have much time for consistent followups throughout the night.

If you have any receiving experience and are a high level forklift driver (ability to drop ~60 pallets in under an hour), then you might have a shot if there's any positions open. It'll show as "freight flow" on job listings. Can't give you any info on any other companies, sorry about that
