Bangalore: It seems like some Tech Company CEOs, except Mark Zuckerberg, is having a really bad time in America. We know what happened to Yahoo’s Scott Thompson. Now it’s the turn of Microsoft CEO Steve Ballmer as a Ranking done by Forbes writer rated him as the CEO who most deserves to be fired.

"Without a doubt, Mr. Ballmer is the worst CEO of a large publicly traded American company today. Not only has he singlehandedly steered Microsoft out of some of the fastest growing and most lucrative tech markets (mobile music, handsets and tablets) but in the process he has sacrificed the growth and profits of not only his company but 'ecosystem' companies such as Dell, Hewlett Packard and even Nokia. The reach of his bad leadership has extended far beyond Microsoft when it comes to destroying shareholder value -- and jobs," wrote Adam Hartung, a Forbes contributor.

He cites Microsoft’s journey starting from Ballmer's appointment as a CEO till today, where the company dropped many products including Zune, Windows CE and many other mobile products. He also notes Microsoft’s share was at $60, when Ballmer took the charge in 2000. Now it trades around $30.

Ballmer might be the only one who heard calls for his resignation from everywhere. Last year, David Einhorn, who runs Greenlight Capital hedge fund, which holds 9 million shares of Microsoft, called for Ballmer to step down saying that the world's largest software company's long-time leader is stuck in the past. "His continued presence is the biggest overhang on Microsoft's stock," Einhorn said.

In the mean time, another survey conducted by Glassdoor.com among Microsoft employees has also rated Ballmer as the worst Tech CEO, who has the least approval rating among employees.

Hartung wrote, “Years late to market, Ballmer has bet the company on Windows 8 -- as well as the future of Dell, HP, Nokia and others. An insane bet for any CEO – and one that would have been avoided entirely had the Microsoft Board replaced Mr. Ballmer years ago with a CEO that understands the fast pace of technology shifts and would have kept Microsoft current with market trends."

Even though Ballmer was successful in growing MS office and Xbox business, his failures, especially losing out in mobile, outpace his success.
