Apparently -- I only heard this once, so take it with a grain of salt -- it's why a Walmart manager is typically cautious when someone with qualifications wants a job. "You want a job as a cashier? Uh huh, I bet you won't show up for your shifts, since you don't need to."

I always thought that was kind of interesting, that being overqualified for a Walmart job might make it harder to just get a Walmart job. (I briefly considered it in a pinch but decided to drive for Uber instead.)

The other reason for the manager to be cautious is that the applicant may quickly become a manager, and the old manager will be out of a job. Or maybe the manager's manager will be out of a job.
