Ggfs, You'd have to see his contract to know if it was legal for them to fire him. When you work for some outfits they have all kinds of conditions from a morality clause to moonlighting to representing the company on or off the clock. NPR may have been well within their rights but was it the right thing to do? And had NPR negated part of the contract by previous non-enforcement.

I think the clencher was the comments Schiller made the day after the firing of Mr. Williams of needing to talk to his psychiatrist and such. Such vindictiveness demonstrates that there was a personal animas involved.

PS You ought to check out Ms Schiller's resume'!
