I saw some other comments that this doesn't work with kids. Not sure I follow exactly. The point is that 5 hour work days can be a better setup than 8 hour days (given that no manager is in your way etc.). What's stopping you from putting those hours in when the kids are in school? I would agree of course that choosing to be employed in a 9-5 job is probably a much better deal when you have kids because of parental leave.
