Tenure: 5 months
Jack Griffin began his tenure as chief executive officer of Time Inc. in September 2010, and became unpopular throughout the company almost immediately. His management style was described as "brusque" and unsuited to the corporate culture. Griffin made frequent and unwelcome references to his religion, and made sexist remarks while addressing the entire company at town hall meetings.
Jeffrey Bewkes, CEO of the parent company, Time Warner, quickly concluded that it wasn't working out. "Although Jack is an extremely accomplished executive, I concluded that his leadership style and approach did not mesh with Time Inc. and Time Warner," Bewkes told the New York Times. Griffin left the company a mere five months after his start date.
