Relief is…
… when a very valued employee asks you for 15 minutes of time with office doors shut, and you are absolutely certain that he is going to hand over his resignation… but when you actually start talking, all he needs to do is vent about a coworker-who-does-not-report-to-you’s behavior. So, in turn, all you have to do is send an email to that person’s boss, as opposed to planning out a help-wanted ad like you thought you were going to have to do. Whew.
