Some days it feels like we’re completely surrounded by rude people from the moment we step out the door. The morning commute alone brings out the worst in just about everyone — not a great way to start the day. In fact, a recent University of Florida study found that rudeness at work is contagious. Big surprise, right? The study showed that, “Encountering rude behavior at work makes people more likely to perceive rudeness in later interactions. That perception makes them more likely to be impolite in return, spreading rudeness like a virus.” Never underestimate the power of proper social etiquette!
