You obviously need to work with him first or have him with you so he can learn it,I had someone with me for a few years I went on holiday and gave him 10 days work over 2 weeks I said try to get as much as you can done,if it rains heavy etc just start where you finished off the day before he said right oh. He new where he was going I came home and he'd done 3-1/2 days work all in the order he fancied,it all changes when your not around I'm not saying it happens with everyone we know it doesn't but I hear similar story's all the time from others. I would never employ anyone who doesn't have bills to pay regardless of how they seem,you need someone that needs you as well.
