It's not possible to move...
I've made a little resume summary of the different options:
Keep it the way it is now:
Work 36 hours per weeks * 2 weeks = 72
+ 9 * 2,5 or 3 hours commute = 24,75 hours
Total: 96,75 hours
New job:
Work 40 hours per week * 2 weeks = 80 hours
+ 10 * 1 or 1,5 hours commute = 12,5
Total: 92,5 hours
This means 4 hours saved, but also 1 day off lost. I'm not sure if this is a great idea, because then he can't use this extra free day to make appointments like a visit to the doctor or to do something with our son...
