Earlier quoted context omitted.
Mixing money and family/friends sounds like it will end horribly. What happens when you don't break even and you need to fire people?
I would say, just brief them at the start "I might fire you tomorrow, go in expecting that, we'll set you up something else if I do. Don't rely on this." Kind of like the way you lend money to friends. That said, you probably shouldn't lend money to friends.
If you can give some of your less fortunate friends/family a job and break even at the same time, it sounds like a win-win for everyone. Certainly if they are currently unemployed.
