Should I hire a family member?
Short answer
Only if you would hire them as a stranger, and only with a job description and a boss who isn't you.
The hard test
Strip the last name off the resume. Would you bring this person in for an interview? If no, the answer is no. The relationship will not survive working together.
If you do it anyway
Write a real job description with real outcomes. Pay them the market rate, not the family rate. Have them report to a non-family manager if you have one, so feedback isn't blood-related.
