A Family IT/Tech Business??

adzoox writes "As I have just hired on my girlfriend to help out with some secretarial work in my Apple consulting, sales, and technical service business, and considering having my brother work with me soon; I'd like to know what the /. readers think about family in the 'Tech Workplace.' Obviously things aren't hectic like a restaurant, but my father and friends have all warned me against mixing business and pleasure and family. Do any of you have successful family owned IT businesses, eBay businesses, or programming/software consulting engineering businesses and what's been or secret to success? If not successful what unique problems did you encounter? How can I make it successful? And most importantly how do you handle authority (tardiness, work ethic, and workplace codes) with a girlfriend?"
