If you need to travel into a major city, that can easily be 45 mins each way. 5 days a week, it pretty much adds up to an extra day each week.
Then there's the benefits to hiring. You now have a global pool of talent to tap, and you can offer for them to live wherever they want. Plus a lot of people appreciate being able to see the kids to/from school.
And just general flexibility is useful. Why shouldn't you run to the shops for a few minutes while things are quiet? Or pay bills, do your taxes, etc?
