> If a person can get another job immediately

This does not happen in reality. There are transactional costs involved in job searching plus additional costs that come from onboarding.

It regularly happens in reality. I know people who have walked out of one job, crossed a street, and walked in to another less than a half hour later. With construction, bartenders, kitchen and waitstaff, bussers, and security it is ridiculously common.

It becomes more common the lower skill the job becomes, as the fungibility of the worker increases.
