Could it be that someone from the community/friends is already “working” on him?
I once worked with/for my relatives (not in-laws though) and after couple of months I realized that no matter how much I contribute in the business, the people in “Khandaan” would always think that they have obliged me and my work would go unnoticed, so I moved out.
I personally think the longer he stays in the same job the more potential things have to get complicated.
