Families spending so much time together can be great but it also has downsides for business. When you work with people you're related to, it's hard to leave problems at the office sometimes. Little disagreements or annoyances that happen during the day might continue even after hours. At the dinner table people still want to talk about work issues they were arguing about. No proper switch-off. And you can't really get away from it all on weekends! You're always around your annoying cousins/siblings. Might be why a lot of family businesses end up not working out long-term. Too many little annoyances build up over time and then bigger fights start. Easier to run a business when you can get distance from people at the end of the work day.
