Though you almost never will technically  need  to specify a reason for leaving, having one ready will make your farewell conversation with your boss (and, later, with your fellow employees) much easier. There are a variety of reasons for leaving: you may have found a position more suited to your life goals, you may be moving away, or you may have have decided to stop working due to ill...
