A family friend built a tire-distributorship business from nothing, starting in his 20s. When he was in his 60s, he sold it. He was always a generous employer to his long-term staff, but he distributed a pretty big share of the sale proceeds to those people who had been with him, even though they had no ownership stake. He recognized all these trusted people helped him build the business from which he profited.
I did the very same thing except the government regulated me out of business. When you treat your employees like human beings they will bend over backwards to make sure every extra personal effort towards productivity is practiced. They consider it their business too, and actually care about overall productivity.
