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...
