32 I have given him a month to buck his ideas up
From your opening post I thought it was going to be some young lad.
At 32 he's hardly a kid that is more interested in chasing skirt than a career, no doubt he's got responsibilities at 32 and you'd hope he'd apply himself in the right way.
Im going to echo pretty much what Wrighty said.
In all honesty some people just aren't suited to certain types of construction, you have to be a natural born problem solver IMO. I've got a decorator (a bloody good one at that) who works for me sometimes, I got him his first job decorating at 18, he's now 37. Over that time he has worked on countless jobs of mine, spent years watching what I and others do and he's always wanted me to teach him other areas of construction. I've tried many times to widen his skill set as really wants to learn but some thing in his head just won't let it click. He can copy parrot fashion but he really struggles to work it out for himself. He's not stupid, far from it. I've just come to the conclusion his brain just isn't wired right for certain tasks and this is a guy that has spent the last 19 years on building sites. But after 10 years of trying, I've given up.
In my case the guy is a friend and more than pulling his weight on the decorating side but if it was an apprentice learning another trade I would have got shot a long time ago. Yes it's harsh but nobody is entitled to a living and you can't carry someone just because he's a likeable guy.
Like I say some people just aren't suited to certain types of jobs no matter how long and hard they try.
