Just over a quarter of Dell's shareholders want company founder Michael Dell out from chairman of the board, an SEC filing late Tuesday revealed. About 25.1 percent of investors refused to vote for Dell's return to the board of directors at last week's annual shareholders' meeting. The lack of confidence was a reflection of protests by the respective unions of the AFL-CIO and American Federation of State, County and Municipal Employees over the company's refusal to fire Dell after settling an SEC suit alleging fraud.
