If what Russ says regarding his non-compete clause in his contract is true, he is not too bright. No major talent signs a non-compete clause (unless he continues to be paid during that time, which Russ says he isn't). Example, if Russ is paid $1,000,000 per year, but has to sit out six month after his contract expires, that means he only makes $500,000 his last year because he won't be working (in radio, anyway) for six months.
Some states, such as Illinois, have made non-competes illegal. You can be working at station A today and station B tomorrow. In other states the talent must still negotiate that clause. Major talent like Howard Stern do not accept a non-compete clause for the reasons previously mentioned. And stations will still sign key talent without a non-compete because they realize the talent will not sign one. Again, if we believe Russ, the reason he was able to get on the air at 105.3 so quickly is because he didn't have a non-compete in effect when he left his old station
Perhaps if Russ had a real media attorney review his contract he would realize not everyone signs a non-compete. When I was starting out at small stations I was always asked to sign a non-compete and never did. Why would I stay unemployed for six months or be forced to move? When I told the management I was moving long distance to make that area my new home and not job hop, they knew I was serious about my commitment and I was never required to sign the non-compete or lose the job. Russ will also find there are enough clauses in that generic contract he signed to dump him at any time the stations wants.
