Public broadcasting has traditionally been at the low end of the pay scale, and has become the training ground for young broadcasters since small-town stations are now largely automated. One of the requirements for any kind of training is that there needs to be someone who is genuinely talented and competent to "pass the torch". With that in mind, I think that every station needs a few "wise old sages" holding down the most important dayparts and programming, news, and production positons. This provides better service to the audience, and gives the up-and-comers critical guidance in their careers. This also keeps a core of recognizable local personalities who should also be key to fund-raising efforts and marketability.
How should those "wise old sages" be compensated? I think that their salaries should be on par with commercial broadcasters in the market who have similar talents, experience, and name recognition. Our "wise old sages" also need the security of knowing that they're valued, and will not be replaced by one of the up-and-comers as long as they continue to perform at a high level. A long-term, annually renewable "no-cut" contract (3 years) would give them that security, knowing that few young people have the patience to hang around waiting for the "old (wo)man" to bite the dust. If either side decides not to renew, both sides have sufficient warning to look for elsewhere to fill their needs. That security, along with the full plate of benefits, should allow public stations to pay a little less in salary in return for a lot more in security.
Up-and-comers will have a chance to learn from good people, and will earn entry-level money. They will be expected to move on within 2-4 years, and should be thankful for the opportunity. If the money elsewhere, either in or out of the market, isn't attractive, they'll have no incentive to move on and make way for new blood.
As far as upper management is concerned, I don't see any reason why the number of people in management shouldn't be lean and mean, with the same focus on fund-raising as commercial stations have on selling airtime. I don't see any reason why the compensation for upper management shouldn't be commensurate with the managers of a commercial station in the market that is delivering similar ratings and revenue. It may be hard to gauge that, since most stations are now part of a cluster, and most managers are responsible for several broadcast stations. Let's go with base salaries that are similar to the local group bringing in a similar audience.
Public broadcasters often have entree into clubs, groups, and societies that are atypical of commercial broadcasters. Rubbing elbows with the monied elite is part of the job. That doesn't mean that public broadcasters have to BE part of the monied elite. With that in mind, I have a hard time justifying base salaries that exceed $150,000 for ANYBODY in public broadcasting on a local level, and darn few of those big-tickets handed out.
Fund-raising performance also has to factor into the equation to provide some incentive, in much that same way that upper management at commercial stations often see percentages in their bonus structures. Bonuses for exceeding the fund-raising targets required to continue operating at the current level of service would add bonus money to the picture. A percentage of the additional revenue could be used for the bonuses - which would be widely distributed to everyone who exceeded their pre-negotiated targets. No more than 25% of the additional funds should go to this bonus structure. The rest should be split between the endowment fund and increasing program quality.
I'm hard-pressed to think of any circumstances where paid outside talent should be brought in to aid in fund-raising. If you have to resort to that, you apparently don't have enough talent available locally. Take the money used for outside fund-raisers and hire more and/or better local people. Keep the $$$ in the community.
Increasing program quality should focus on better serving the LOCAL audience, either with more and better local programming, or purchasing programs that focus on local history, interests, or educational opportunities. Ideally, locally-produced programming that serves both the local audience, and is good enough to attract the attention (and revenue) of a wider public-broadcasting audience ultimately helps both the ratings and the bottom line.
Thanks for reading this far. I'm sure you'll feel free to point out the flaws in my proposal...
