【Elon Musk bans Twitter employees from working remotely】 Elon Musk has banned Twitter employees from working remotely, saying they need to spend 40 hours a week in the office unless he gives his express permission otherwise. Bloomberg reported from the company’s first official all-hands communications from Musk since bought the platform. He said workers need to prepare for “difficult times ahead” for advertising-led business like Twitter, and that he wants to see subscription fees account for half the company’s revenue.
