If a billionaire “invites” you somewhere, you’d better go. Or be prepared to suffer the consequences. This past May, hedge fund kingpin Carl Icahn announced in a letter to his New York-based staff of about 50 that he would be moving his business operations to Florida. But the 83-year-old Icahn assured his staffers they had no reason to worry: “My employees have always been very important to the company, so I’d like to invite you all to join me in Miami.” Those who go south, his letter added, would get a $50,000 relocation benefit “once you have established your permanent residence in Florida.” Those who stay put, the letter continued, can file for state unemployment benefits, a $450 weekly maximum that “you can receive for a total of 26 weeks.” What about severance from Icahn Enterprises? The New York Post reported last week that the two dozen employees who have chosen not to uproot their families and follow Icahn to Florida “will be let go without any severance” when the billionaire shutters his New York offices this coming March. Bloomberg currently puts Carl Icahn’s net worth at $20.5 billion.
