Definitely depends on the family, my first job I worked at McDonald’s with two of my sisters at one point my dad and my sister in law and brother in law! I’ve helped at my dad’s and sisters company lots of time. We have a very close family and have worked together in many ways for many reasons. I think if the family has issues or is likely to argue it might cause problems.
For sure a good family work relationship is very important,to help achieve successfully.
