Discussion on: What should I do when I get hit on by colleagues?

I'd say be blunt upfront. But politely decline. It's good to get rid of this in the very beginning before it becomes something else.

You'll never be able to keep everyone happy, it's life.

I for one have been blunt if you get the hint in it. It has always worked just fine.Except for one time. But that's how it is.
