Amazon is firing back at New York Times exposé that detailed the Web giant's "tough" and "combative" workplace culture.

In a Medium post Monday, Amazon's Senior Vice President of Corporate Affairs, Jay Carney, specifically took issue with a quote from former Amazon employee Bo Olson, who said, "Nearly every person I worked with, I saw cry at their desk."

Carney, who previously served as President Obama's press secretary, claims the piece's authors, Jodi Kantor and David Streitfeld, failed to "check or vet the anecdotes and quotes from sources willing to go on the record," and suggested that sources who painted a negative picture of the company culture "might have an axe to grind."

"Here's what the story didn't tell you about Mr. Olson: his brief tenure at Amazon ended after an investigation revealed he had attempted to defraud vendors and conceal it by falsifying business records," Carney wrote. "Why weren't readers given that information?"

The Times doesn't look to be planning a retraction any time soon, however. In a separate Medium post Monday, the newspaper's Executive Editor, Dean Baquet, disputed Carney's claims about Olson.

"He said he was never confronted with allegations of personally fraudulent conduct or falsifying records, nor did he admit to that," Baquet wrote. "His one quote in the story was consistent with those of other current and former employees. Several other people in other divisions also described people crying publicly in very similar terms."

Baquet reiterated his support for the story, calling it an "accurate portrait." Amazon's PR boss disagrees.

"The bottom line is the New York Times chose not to fact-check or vet its most important on-the-record sources, despite working on the story for six months," Carney wrote in response to Baquet. "I really don't see a defensible explanation for that failure."

Carney pointed to May email from Kantor to Amazon's vice president of public relations, in which Kantor said she did not want the story to be "a stack of negative anecdotes from ex-Amazonians."

"We decided to participate by sharing much of what Ms. Kantor asked for, yet the article she specifically said they were not writing became the article that we all read," Carney wrote. "And, despite our months-long participation, we were given no opportunity to see, respond to, or help fact-check the 'stack of negative anecdotes' that they ultimately used."

On Twitter, Kantor pointed readers to Baquet's response.
