The customer list of a radio station "should" be the most valuable piece intellectual property in a small to medium market station. When a salesman deals with and creates relationships with clients he could very easily make personal notes about all the accounts he dealt with and try to use them to make commission based sales at another station. Can you tell that I've had this happen to me before in another business?
Hypothetical situation: If a top salesman for WWTF quit and went to work for WNEU because he was offered more money it would be wrong for him to contact the clients he had worked with at WWTF and solicit their business for WNEU. It's likely that the owner of WNEU hired the salesman from WWTF because he already had good contacts he thought he could quickly sell spots to. That would be stealing clients from his former employer and the salesman could be sued by WWTF and he would likely loose that suit. In this case I don't think it would matter if WWTF had a non-compete contract with their salesmen or not, stealing intellectual property (clients) is just plain stealing. Now, if this salesman went to a Chamber of Commerce meeting wearing a WNEU shirt and ran in to some of his former clients from WWTF and those former clients told him they were interested in advertising on WNEU he wouldn't be stealing. It would be smart to have those clients sign an affidavit stating that he hadn't solicited their business and that the client had sought him out (before they signed any contracts with WNEU). This would help in his defense when he gets sued by WWTF.
For the sake of argument, lets say that Marty and Linda aren't using their real names. If they had a non-compete and their contracts expired and they went to work for WYCT, they probably couldn't use the names Marty and Linda... even if WXBM hadn't trademarked the names, also the name of the WXBM morning show would still be WXBM's intellectual property. In this case it's the talent that matters, not the name, so it wouldn't be a problem for WYCT and Marty and Linda to come up with something new. Also, since Marty and Linda have been a staple in Pensacola radio for so long, they probably have negotiated a contract with WXBM that does not include a non-compete.... at least that's what I would do.
For something really complicated, lets say there's a DJ running the 11 PM to 5 AM graveyard shift at WXXX. WXXX gave him his first job in radio and he was taught everything he knows about radio by the staff at WXXX. Like all employees at WXXX he has signed a standard non-compete stating he won't work as a DJ within 100 miles for one year after he leaves the station. This DJ comes into some money and quits his job to pursue his dream of owning a radio station and buys an AM daytimer in the same market. He goes in and starts running the station by himself using a satellite format and some automation. He is not in violation of his non-compete agreement with WXXX by owning and operating his own AM daytimer because he is using a satellite fed service and is not working as a DJ. On the other hand, the intellectual property he has from WXXX is everything he knows about running a radio station. He is now in competition with his former employer at WXXX. This could go anywhere.
Non competes are weird. When my attorney told me to have my employees sign non-competes he included one for me, an owner of the corporation, to sign. I didn't sign it. I also wouldn't sign any of the documents concerning drug and alcohol use on the job and proper use of company equipment or anything else. Those forms are all in my employee file, blank.
I had one employee that had cold feet about signing a non-compete fearing the worst since he didn't know any other field he could make a living in. In the end I let him keep his job without signing the non-compete and guess what, he screwed me over a few years later. I had the case set to go on the basis of stealing Intellectual Property, but Hurricane Ivan destroyed everything this man had and there was nothing for me to go after. If my dad was still running the shop, that guy would have had his knees broken, or worse.
I've had two other employees that wanted to leave on good terms and they negotiated a release from their non-compete and I've made it clear to everyone that they have the option to do this if they want to leave my company. One former employee agreed to pay me commission on any of my customers I lost to him for 2 years after he resigned. I had one employee that went to work for the county, so since I only had state and federal contracts, no city or county level contracts, I let him go with my blessing. That guy still sends me work on a regular basis and picks up some pretty good bird dog money.
