Nell Scovell, as you may well know, is a fine writer of all things comedic. Once upon a time, she wrote for David Letterman and it wasn't the happiest experience in her life. Ten years ago in this article, she wrote about the experience and how Mr. Letterman's predilection (eventually admitted) for having sex with staff members created an uncomfy and unfair work environment.
There is a sequel. Not long ago, she sat down with Dave after he finally (finally!) read the article and they discussed what it said and what he did. Here is her account of that meeting.
I was once a huge fan of Dave as on-air talent and an admirer of some of the things I knew he'd done off-screen and some of the ethics he embraced. Some (not all) of the admiration in both categories faded due to later actions. Obviously, I've never had anywhere near the hiring/firing power he had but when I worked on staff on TV shows, I learned that sexual involvement within the workplace is usually bad for All Concerned, including the surrounding people not directly involved in the sex. And it's bad in many ways, even beyond the issue of who gets hired and/or fired.
