Not because I have any on going business with family members but because of what I have seen and stories I have heard, to an extent one or two things I can relate with but do you think it is also true that they're the worst set of people to have a business with. Some have also said that, no one should have anyone like family members who they can not arrest to be in charge of their business.
They can borrow money from you and end up not paying back making your plans look stupid and leaving you disappointed and because they are family, you can not take strong decisions against them in anyway. What are your opinions? I love family more than anything, but they seem like the worst people IMO. My major advice is never to borrow them money and if you intend to give, give without expecting a dine in return.
I advise you not to do any kind of transaction with close relatives. If someone in the family has a business and requests you to work there, you should not join that job and look for a job somewhere else.
Strictness can be shown towards relatives or family members if they work under you. And the level of that strictness is also comparatively higher due to prior acquaintance. If there is any financial loss to that business, the blame will be placed on that relative employee first.
Many such incidents happen in reality because many family members find opportunities and do not remain responsible and fair as the business is not theirs. They get maximum benefits from it but are not responsible for the work.
