Working an overnight job that's an hour away?

If he works only 6 days on Fridays, let him get all the rest he needs on Saturday. I don't mean the whole day Saturday, but whenever he has got enough rest by Saturday evening, you can do whatever you and him want to do for the whole weekend. And make sure that he goes to bed early Sunday to get plenty of rest for Monday. He should have a fresh start by Monday. I think it's just taking him some time to get used to it because he is not used to working nights instead of days. I know there lots of jobs that work you 12 hours for 2 weeks. Some work day shifts and some nights. After 2 weeks the employs change shifts and that's hard because the ones that are used to working nights have to get used to working during the days. The same goes for the other ones.
