My dad has been hiring a bunch of guys to do some really heavy "lifting", and they are ridiculously cheap. For example they removed a huge tree for $450. I was stunned when I heard it - it generally costs several thousand. The numbers didn't add up - it would cost more than that just to dispose of it at the tip. But, they seemed happy enough to do it, although it still didn't feel right. Other than the fact that I'm not particularly comfortable with them being underpaid (I believe in fair pay for fair work), I have to assume they're uninsured, which worries me. If they ever got hurt would we be at risk at all (assuming the work they were doing was actually legal)?
