His Dad lives at the bottom of the hill and he is moving in with him to take care of him. He plans on living there after his Dad passes, at least that is what I understand.
As far as productivity, he is a skilled worker for sure, but Dad has created the need for him. Basically my Dad wants someone to do whatever he wants when he wants it, by keeping an employee around, he can have them do what he wants at a moments notice, the rest of the time the employee is doing things that should be hired out. The best way for me to explain it is with an example of what he does. He had my Dad buy a couple welders because they were good deals, then he fixed one rather easily, the second one he pulled apart, bought parts, put it back together, tested it, had to pull it apart, buy more parts, put it back together....... you get the idea. In the end Dad ended up with two welders, on for the Employee’s shop and one for Dad’s shop, but it cost more than what buying two new welders would have cost between parts and labor, not to mention the time the employee could have been doing something more important. My Dad doesn’t see things the way I do, I repair things because I can’t afford to buy the new version, my Dad created a job position to repair things that in the end he pays more than a new version costs while complaining that he needs to get this project done or that project done and there isn’t enough time.
So in the end, the employee can fix anything, can make anything, but should he really be doing either?
