They should have to sign a waiver that this is a work at your own risk job, for crying out loud people sign them to go bungee jumping, parachuting, and all kinds of other things! if they want to have money in their pockets they will do it!
When I first started my home improvement contracting business, I was VERY slow the first winter. Myself and my only employee would wake every day at 7:00am drive to a roadside, park the truck, and each take a side of the highway ad pick up all the aluminum cans we could find. We would keep filling bags until around 5:00 in the evening, walk back to the truck drive up the road and load all the cans (or any other metal objects we could find) and take them to the junk yard. We averaged about $200 per week each, not a full time pay BUT we survived!
Even when I was a kid, growing up in the antracite region I collected coal in buckets and sold it to the local reidents to burn in their hand fires.
Eventually I had enough money for a motorcycle, and I had a welder that I sold coal to make me a buggy I could hook up to my cycle to make my job easier, doubled my output!
Thats the difference between me and those people I guess I have too much damned pride to take anything without earning it
