I believe you should create a company where the employees are proud to say they work for "ABC Landscapes" I study the top 20 companies to work for and there practices. (Publix, Car max, Zappos, Whole Foods, etc) and see how they treat their bottom feeders.
You can also read reviews from employees at glassdoor.com as they review the job and how they like working for the specific company.
I believe the OP was referring to the type of employee that is a linchpin to the company. If you lost him, it would make life hell as he is not easily replaceable.
There tends to be a large amount of micromanaging in this business. How do your guys behave when your back is turned?
