Even in family businesses or especially there and in families, boundaries are essential I think. Work and responsibilities have to be organized, at least in my opinion. That creates a safe work environment. I know I certainly would throw a fit if I had the feeling that there were no clear structures etc or that someone took advantage of me and/or didn't communicate. Imbalance causes a waste of energy and that can be very frustrating - maybe a little rant here and there helps you discover what makes you "explode"
