If you have a job of any kind, there are two guarantees: 1) you will, at some point or another, make a mistake. 2) You will not be able to look your co-workers in the eyes after the office holiday party. Often, these two things overlap, but not always.
Everyone messes up at work—unless you're my boss reading this, in which case, I'm the one exception! Most work mistakes can be easily resolved and/or quickly forgotten about. But sometimes, messing up at work can have major consequences and the experience can haunt you for the rest of your life. If you've made this kind of work mistake, rest assured that you're not the only one.
