Where I work we have a caretaker/handyman who works 6:30 - 10:30 2:30 - 6:30, so he's free in the middle of the day.
He's very reliable and good at his job. If I were to employ him to do some odd jobs for me, what are the implications for me?
The cash in hand is not about saving me money, I'd prefer to do it properly and make sure he pays the tax, but he's a "simple" man and doesn't want to complicate matters
If I refuse to pay him cash I think he will refuse the work, but even if I pay another way, that isn't going to prove he (or any other tradesman) pays the tax, is it?
