(FORTUNE Magazine) – Michael Eisner isn't the only king whose subjects want him deposed. His 43% no-confidence vote was the highest in recent memory, but according to an analysis by Institutional Shareholder Services, six other companies have seen between 28% and 42% of shares voted against a sitting CEO in the past year. "We're seeing more large investors voicing their concerns, especially at the ballot box," says L. Richards McMillan II, a partner at Jones Walker LLP. We're guessing it's cold comfort for Eisner to know he's not alone. --Christopher Tkaczyk
