I have volunteered with the Interfaith Night Shelter Program, and when the families were at my church, almost half were single dads, some working, trying to save enough for a new place to live while they also tried to repair their credit, help their kids with homework, etc.  Some were recovering from surgery or injuries (not job related) that had nonetheless cost them their jobs because they couldn't work.  They were all involved in a plan to resolve their situation, and almost all of them were working that plan very hard.
