There is a website...
http://www.careersinthevillages.com/searchJobs.asp although now they refer you to the local newspaper for most of the opportunities but it may be of some help. The HR department in TV also, at least it used to, has binders full of job openings in TV. I still work full time as well as my wife but not in TV. We intended to work a few years after we came down and although we work outside TV, neither if us really had much of a problem finding jobs.
