1. a test of skill or ability; a contest
2. rivalry between two or more businesses striving for the same customer or market

It has been said, that your partner always brings out the "better" side of you, in most cases that is true. But with working in the same place as your significant other, it can bring out the "competitive" part of a person. In my opinion, I believe working with someone you are dating, may not necessarily always benefit you, your company, or secure your position. Competition has its positives and its negatives, but it is all up to the individual to use it properly, and not only to his or her advantage. I strongly believe that when you are dating someone whom you also work with, a competitive streak will eventually come out; it may start off as your attempt in trying to "impress" your partner, but in the end it could just as well evolve into a small rivalry with one another. A little competition is always healthy, but if you are only doing it for personal reasons, that’s just wrong and unnecessary. Not only does this complicate your relationship, but it brings tension within the company, fellow co-workers and possibly even the customers.
