How is a non compete agreement enforced in this job

If you bring business from one employer to another they can enforce a non-compete. Here's an example. You drive for Billy Bob and Billy Bob has a contract with International Cotton Candy. The shipping clerk at International Cotton Candy likes you because he thinks you're cute. You quit Billy Bob and go work for Sally Sue. You call up the shipping clerk and convince him to use Sally Sue's company instead. You just used the inside knowledge gained through your employment at Billy Bob to steal business away from him. That's where the non-compete would come into play. The other are they try to enforce is you working elsewhere before repaying the loan for training. But this has been ruled illegal in a settled class action suit with CRST, CR. England and Western Express.
