Everyone I know that works in a location works shift patterns or other non 9-5 jobs. My wife might start at 7.30 am one day, or another day not finish to 9pm.

If you're working 9-5 every day it's increasingly unlikely you need to be in a specific place to do so. Those who do work in specific places tend to have to cover a far larger range than 9-5 and thus require alternate child care arrangements anyway.
