Everyone lies, right? Despite being taught since birth that telling the truth is the right thing to do, research suggests that Americans average almost two lies per day. And since we spend so much time at work, it's not surprising that many of those lies are told at the office. According to a long-reported survey by psychotherapist Dr. Brad Blanton, a whopping 93% of respondents out of forty thousand Americans admitted to lying "regularly and habitually in the workplace." And don't we all agree that the remaining 7% are probably lying to themselves about not lying? Let's face it, we've all called in sick when we weren't officially down with the flu and blamed "horrible traffic" when we were simply running late. They're little white lies, and everyone pretty much ignores them. But sometimes, a few well-chosen fibs can actually help propel your career. Here's a handy cheat sheet.
