Them? If you're planning to sleep with more than one co-worker then there will be serious problems in the work area. Think about it, what happens if you end up in the same room as the persons you've slept with. A little on the uneasy side isn't it? So I guess my answer is don't do it. And even if you meant there is one co-worker you want to sleep with, I still think it might be a bad decision. Whether you sleep with your co-worker or not, you're gonna be distraced...who are you kidding? You're just gonna want it more once you had it. If it were me, I would. Take my advice, if you're planning to work where you're working at for a long time, don't do it...it's not worth it. I know the temptations are tought but I've been in those situations and the end results were bad!
