We've yet to hear details of what this really mean, and if this CoC is applied fairly. It sounds like the violation i a) based on a particular interpretation of the memo, or b) based on the subjective offense of other employees. This sounds like the "cultural fit" loophole of the left.
> That's different than being fired for an idea
Is it? Have all the ideas you want, just don't express them, even in forums than are specifically for that purpose? Why isn't the leaker being punished?
> If I started onto my company's social intranet
There are plenty liberal/left essays floating about the google intranets, this is not you average employer.
> he created a hostile atmosphere
Did he? The leaker, and those who misrepresented the content of the memo seem to be implicit in that.
> This resulted in bad press
So does any whistle-blower. But again - He did not leak the memo.
