Tree removal is a bit different than trimming. I wouldn’t have a big tree removed by randos for sure, but maybe a small tree. I wouldn’t hire people who I didn’t think knew what they were doing to go climbing in trees with chain saws for their sake more than anyone else’s.
Regarding getting sued…I’ll try to keep this brief:
I installed solar on a house as a subcontractor for a sales company.
I hired a roofer, not my employee, to do a little work on the section I was doing solar on.
Without my knowledge or taking any part in this, the homeowner hired the roofer to do work on another section of the roof.
When doing that work, after my solar job was completely finished, the roofer hired someone to work with him and that person fell off the roof and was seriously hurt.
He sued the person who hired him and the homeowner. Homeowner’s insurance company countersued me and the solar company that hired me. Solar company that hired me countersued me. (not sure countersue is the right word, but they sue saying, in case they lose, they don’t wanna pay). I had zero connection to the person who got hurt or the work they did. I’m the only party who didn’t sue anyone - maybe the roofer didn’t.
Anyway, I paid a lawyer $5k for responding to stuff. I (obviously) didn’t lose the case.
Point being…people sue.
eta: I was mad at the solar company and never worked for them again and, at first, I was mad at the home owner for suing me. I called them about it, but they said it wasn’t them, but their insurance company.
eta eta: Of course, undocumented people are probably going to be afraid to sue anyone now.
