We all know how it starts. You meet over by the vending machine; he buys you a Nutrigrain bar; you tell him you like his cufflinks. The next thing you know, you've been dating for six months and the whole office now refers to you as "the two-headed monster." Yes, every office has an office romance or two (or ten, depending on your industry), and they can be good or bad, fast-burning or long-lasting--or just plain embarrassing. They can also be mysterious, under-the-table affairs, but no more: a poll of over 3000 workers has led to concrete findings about office romance, and we've compiled the results here, just in time for Valentine's Day.
