It would not surprise me if Russ Martin is back on the air in a week. I am thinking that this could easily be done with a "behind the scenes" agreement, covering restrictions about content. First, he can say, on the air, that his attorney won't let him talk about the case (he has already provided something to that effect in an "official" statement). Secondly, he simply could agree not to say anything which deprecates women (for example, any talk about mistreatment of women or violence against women or discussions about how to take advantage of women). That would greatly restrict what he could talk about, judging by the subjects of previous broadcasts, but since he has been known to do whole shows talking only about how he sprained his ankle or "accidentally" took a drug,he could continue, most likely, without difficulty.
The real question is whether or not his ratings, defining his listener base, are sufficient to garner continued advertiser support and, if so, it would be foolish (from a business standpoint) to cancel his show, when such an approach (which incorporates a mutual agreement, covers limited on-air restrictions and occurs after a sufficient "off the air hiatus"), is generally considered appropriate in the broadcast business. In this type of situation (an on-air personality accused of a crime), a one-week suspension is usually enough to satisfy any public criticism, by those who otherwise could say the station had treated the situation lightly. If this approach could protect the station against potential loss of revenue, then it really is the correct business decision. Honoring the well known and highly tauted right of "innocent until proven guilty" can be used to considerable advantage to allow management quite a bit of leeway in avoiding cancellation of a proven personality, who is bringing in significant income to the company.
I look for Russ Martin to be back on the air on Monday with no significant announcements, but certainly with a repeat of his "can't talk about it, because my lawyer says not to" and then production of "shows" with subjects other than those which might be construed as relative to the matter before the courts, or would prejudice his case or put the station in an uncomfortable position with women's groups or "sensitive" listeners. Protection of revenue is paramount and this is an acceptable approach, which actually has some viable public relations caché, with the management enjoying the position of protecting individual rights and not "rushing to judgement."
