Well, I met my boyfriend (of 4 years, now) at a job. Although, as justamom mentioned, it
was just a summer job for me.
Now I work in a small place, less than 30 coworkers. We joke about how we are the "horny" store (out of the entire local chain), because people are always hooking up with and/or dating other coworkers. We have even had coworkers leave our store because they were dating managers.
I get to see all of them tonight at our XMas party, though.
I have to say, it totally depends on the people you work with. I adore all of my coworkers, and we all party together & stuff quite a bit. (Very unnatural, really

). Some people are more mature than others. The gossip is a factor, but not very much so.
Most of our gossip is company-related, not person-related.
Back to the XMas party... our manager asked us all to write down 1 or 2 things about us that noone knows (like "I have a 3-legged dog"- just weird stuff) for this game we'll be playing. Someone mentioned something I didn't catch, and then she (the manager) said, "No, you can't put 'I slept with a coworker'. That would be everyone in the store!". So, as you can see, we're all pretty good natured about it
