You work for a large international company, and a co-worker tells you that he has no plans to return to his job after he takes his annual two-week vacation. You know that your department cannot meet its deadlines shorthanded and that your department will need at least two or three weeks to recruit and hire a qualified replacement. You also know that it is your company's policy not to give paid vacations to employees who do not agree to work for at least three months following their return. What should you do? What points would you make in a confidential email to your boss? What points would you raise to your co-worker?
