Oracle CEO Larry Ellison served notice on competitors yesterday but saved his toughest talk for the UBS investment analyst who recently floated the rumor that Oracle would dismiss more than 13,000 Sun employees, or half its total workforce. Ellison called that claim "garbage" that was "highly irresponsible" and then set the record straight: Oracle will be adding employees.The claim of mass layoffs originated from UBS stock analyst Brent Thill and was then picked up by Bloomberg.com. We wrote about this last week in a post called Oracle-Sun Layoff Prediction: Hold Analyst Accountable.

Yesterday, after speaking for about 10 minutes on his vision for Oracle-Sun, Ellison tore into the analyst (not by name) who made the original claim and the various analysts and media who picked up on it without question. In my experience, it was an unprecedented set of comments from a CEO to analysts and the media, but I think it was a brilliant stroke by Ellison because in sharing publicly and angrily his heartfelt reaction to those reports, he let Sun's 27,000 employees know in unmistakable terms that they have his full and unwavering support.

Here's what he said via my transcription of his remarks:

"The last thing I'm going to say is, and I'm sure you've heard, I was very upset to see articles from analysts and in the press saying Oracle's gonna lay off half of Sun's organization. Half the Sun employee base, we're just gonna lay them off. I mean, that's a highly irresponsible thing just to make up and print.

"So I think the people, whoever did that, should be ashamed of themselves. The Sun people went through enough angst without having to read this garbage that you're writing. The truth is we're actually hiring 2,000 people over the next few months to beef up these businesses, and that's about twice as many people as we'll be laying off.

"So we're hiring, not firing. We're not cutting Sun to profitability, we're growing Sun to profitability."

Well said. As we wrote in our post last week about that rumor of imminent mass layoffs:
