If you are looking for a friend w bennies, or to rush into something, don't look for it at work. Such relationships are fraught with peril to begin with, and having it with a co-worker complicates things more.
OTOH, if you are going to pursue this like a mature adult-take the time to get to know the person, gradual progression in PDAs/signs of affection, not sending your pt supervisor or center manager to break up for you if things go sour-you shouldn't worry about catastrophe, even at thw work place. The key is being honest, open, and fair, with yourself as well the other person. If you know early on it probably won't work, don't be shy/cowardly and not break it off in a mature/peacefully manner. Afterall, even if they weren't your co-worker that'd be bad because it's just unkind, not decent, and they end up the ones stalking you and necessatating you getting a restraining order on them.
It is hard to find someone you have real chemistry with, and you two MAY have it. Handle this on a mature, adult fashion and you should be fine. Remember, take your time, and be discreet.
