Plenty, only competent people, though, or those who don't think they are mind-readers or can do whatever they think they should.
I bet we would get long fine, as you seem to have been around the block a bunch.
I got ruined, working with a highly-experienced (40 years in BIG timber, I think his biggest fell was 330', at Rockport State Park, onto gravel beds on asphalt), competent person doing really dangerous tree work for over two years (springboards, Silvey dual ram jacks, skidder, banging over huge and rotten trees to get down amongst huge green trees), and there were the incidences where employees have nearly killed me or blinded me or hurt me, or I've had to hold their way too hands so they don't hurt themselves or anyone else.
Most residential work is straight-forward, safe, and easy, IMO, just big or small elephants. Sure, there is tons of stuff to learn, but mostly employees' equivalent (especially their scope of work, not the climber's/ feller's) is like building a garage, not design/ build the TaJ Mahal.
Seems to me, the hardest part is dealing with employees who know better than me, and can read my mind, even though they mostly pick up sticks, feed a stick-eater machine, run a rake, drive a pick-up and trailer. I self-lower most stuff, as it's easier and safer.
Once I had a plan (where I did all the planning, decision-making, and laid down full-drop-zone sized pieces, repeatedly) where one groundie was to catch/ hold the tip-tied log, allowing it to swing into free space, but little did I know that groundie #2, fresh back from taking a leak or whatever he was doing behind the shed, snuck in from behind, grabbing a rope, and swinging the log into me (far from help, up a backyard oak), because 'he wanted to help'.
Do you let guys like that stay around?
How many ex-cons do you have working for you?
How many ex-cons would you want knowing the security of 10s of thousands of dollars of equipment?
With how many high-end clients would you be honest with about your source of employees? . I know the people with the waterfront house don't want tweeky-mctweek or brain-burned used-to-be tweeky-mctweek at their property.
I have to do a little land clearing job for clients. Their 20 year-old, 20x30 shop is not up to par. 52' x 52' should hold their mini-x, tractor, splitter/ root-grapple/ and other implements, Gator, etc, etc, etc, etc.). People who are spending $100-200k a year on improvements/ renovations on their 10 year old house, and 20 year old property (used to be just forest), DO NOT WANT CONVICTS!
I'd start losing customers fast. Would you hire a company to come to, into your home who is an ex-con?
Once burned, twice shy.
How many times have people nearly killed or blinded you or crushed you, and then you have gone on to be willing to work with people like that?
