Tutorial on how to hire your own sims you made, to work in your Restaurant

Well, I am glad for this work-around to hire sims that we've created. But is nobody else disappointed that you can't hire sims you actually play? Once you play their household, they'll lose their job.

Although I guess it's pretty easy to re-hire them, and they don't lose the skills they've earned. It's just disappointing that they've made this so complicated. :\
