does anyone use contracts for their employee, with statements containing items like: should you elect to go into business on your own, you will not do business within a 50 mile radius of ( your company)? and : no moonlighting in any field that involve lawn care and landscaping? if you do, is it any good? does it work? and if it is good could you send me a copy so i can get an idea on how to set up a good one.
