This mistake seems so obvious that you may be wondering why I included it, but it is actually an issue that many firms have experienced. Office romances are bad for you, bad for the other person, and bad for the firm. This means no dating or flirting, which can be a recipe for disaster.
Moreover, if you are a law clerk hoping to be hired permanently by the firm, you may risk being passed over based upon a perceived lack of judgment for engaging in an office relationship. Think you can simply hide the romance? No way. They always come out in one way or another. This is one mistake that you must simply avoid.
