As any job search advisor will tell you—and most hiring managers will happily confirm—a few little social graces can go a long way in the professional world. Genuine manners are a sign of intelligence, empathy, and complex reasoning skills, all of which are valuable in the workplace. And there’s actually a darker side to this equation: Like it or not, class background is an unconscious but important factor managers rely on when making hiring decisions. So your manners, gestures, clothing, and the register of your speech should ideally reflect an upper class upbringing (regardless of your actual upbringing, which is none of your employer’s business).One of these class-signifying gestures involves a ritual known as the thank-you note. Master this move and make sure you execute it in a natural and graceful way, as if you’ve been crafting hand written thank-you notes all your life. Keep these tips in mind.
