If you cannot give your family members a chance to take on responsibility and let them make mistakes they will end up in an confused state that only leads to internal family stress.
This a very good reason why next generation family members need to get away from the family business and work outside in a couple of other businesses for a while. Sometimes parents are too protective of their children and tend to keep making decisions for them and never let them have command or control of what they do. They are overly protective and we end up with what I call Golden Children.
On the other hand, some parents are unreasonably tough and cause all sorts of stress and conflict for those on the receiving end. This stress is usually felt most within the next generation's marriage. The daughter-in-law or son-in-law is then is a no-win situation when they protest that their partner is being treated unfairly.
I have seen this in a couple of family businesses where an in-law has complained. They are then persecuted and it's not acceptable. In fact, it is bullying of the very worst kind and the emotional effect is long lasting. Regrettably it has lead to suicide.
