Apparently hell hath no fury like a departing Associated Press business reporter. In a resignation letter obtained by Poynter, Janna Herron, an AP reporter for the past five years, blasts leadership:

I’m the 56th person to leave since the newsroom’s management style turned negative and mean-spirited three years ago. And I’m sure I’m not the last. I just couldn’t do it anymore.

So, best wishes to everyone. You’re all better editors, reporters and writers than what you’ve been told, and you deserve better leadership.

Well, consider that bridge burned.

And in case you were wondering, Hal Ritter is the AP’s Business Editor.
