Of course it depends who the father/son is. What is the point of building a business if not to see it continue into the generations. What does one expect to do with a business upon retirement, just sell it? Does one really put all their kochos into something just to turn it over to someone else?
On the other hand, children should not be cocky and just assume, oh, i don’t have to worry, my parents will give me a job, i’ve got it made. No one should just assume that they have it coming to them. Everyone should understand, that any business was built on blood, sweat and tears and that anyone who comes to work there has to pay his dues, even a beloved son.
When a father gives a son a job, the son must come to work with respect for his father AND for all the employees that were there before him. Even if he is now in a supervisory role. He must learn how to balance the job he has with the respect he must show. Because no matter what role he takes on, he is not the BOSS, he is just like everyone else, an employee.
