I think husband and wife are the ones who can most safely work together as one wont likely or is extremely likely to have a yetzer hora to steal from or sabotage the other….
After that I would say a father and son business could work as long as there are clear boundaries and the son has respect for his father. There have been stories where kids pushed their fathers out of the business nebach…
Siblings can make it work but its tough, again, boundaries have to be clear, everyone has to understand that “plony” is boss even if he or she may be the youngest sibling. Dont mix family with business. Keep things businesslike and professional thats the bottom line.
I would say most would agree that its smartest to avoid working with your brother or sister in laws.
Working for a father in law can be ok but again depends if there are also brother and sister in laws working there and if theres room for complications…
Just think it through and see if the personalities involved can work together and are mature people who can be professional and not mix family with business.
