Yes mate, give him ago. I know a deaf guy, who also can't talk, it's a sign language, I don't know sign or nothing but he lip reads me wen I talk to him. He works as a maintenance / outside guy for Speke McDonald's, does all there pressure washing outside cleaning. He knows we're to be at wot times, and I think the world of for getting out there and keeps going in life. I offered him a job working for me but he says he was happy to work at the mcdonalds.
Really nice guy always up for a laugh and joke, the little poop thinks it's funny to rob the washing up liquid out me bucket and hides it on me, so I go slash all the bottoms on the bin bags in the bins..........
2 can play that game my friend haha.
But serious I think the world of him and would have no probs working with him.
If there is a problem with insurance, then sub work to him, as he couldn't be any more keen, if he keeps returning for work.
Good on you rhinoman
