A new book claims that Bill Gates’ intense work ethic and intimidating presence have fostered a culture of fear among employees at the Bill & Melinda Gates Foundation. The book, “Billionaire, Nerd, Savior, King: Bill Gates and His Quest to Shape Our World,” describes meetings with Gates as akin to a king holding court, with employees fearing his scrutiny and questioning. While Gates Ventures has dismissed the allegations, the book has raised concerns about the foundation’s work environment.
