Thanks guys. I take care of her mobile phone bill and bought her an iPhone already. She has no qualifications. She has great flexibility due to the nature of the business we work in. During a quiet period last year she went home an hour early every day (on my insistance) and now it's really busy but she's coming in to work on Monday (public holiday) to keep up with everything.
It's an unsual industry and something others offer to work for free in for 12 months to break into it. She came to me that way actually. Offered to work for a day a week to get experience (but I chose to pay her) and after 3 weeks I hired her full time.
She started as a 20yo on $31K, then it was raised it to $33,800 a year ago. Maybe if I raise another $60pw to $36,920 for now.
I like the percentage of profits thing, but I think I'll keep that up my sleeve until she's been here another couple of years and has gained more experience. I've been teaching her different aspects of my job until she masters it, then we move onto another area for her to learn. Eventually she will want to leave and do it on her own, but maybe a share of profits will hold her longer.
She's very happy and loves working with me so no fear of losing her at present, but I want to ensure it stays that way.
Thanks again for your input.
