I have worked in several family businesses. The question of family direct participation in the business is a tricky one. I have seen it done well and I have seen it done horribly. The worst is when it is clear that but for being a family member, they would not have a job at the company. I don’t think it matters as much whether the person is a member of the family, it is more a question of if the person is competent and needed in a particular role for their skill set.
