"Banker's hours" or "banking hours" is a longstanding U.S. idiom for very short days. It comes from a time when retail bank lobbies were only open from, say, 10:00am to 2:00pm, Monday through Thursday.

I'm exaggerating slightly for effect, but probably not much. Going to the bank used to be a highly inconvenient thing for people who worked jobs that did not let them pop out for an errand whenever they felt like it (manufacturing, retail, service, etc). So the term "banker's hours" also has a connotation of the privileges of the rich--people living lives of leisure and freedom. (including the bankers themselves of course)

Ah yes that is true we can leave pretty much whenever we want for however long, as long as the work gets done. Thank you for reminding me of yet another perk that I didn't fully take in.
