as long as you don't encourage it.........i'm all for the long & drawn out process........remainin nice, not flirtin, nothing suggestive........eventually they git bored & move on
Just let them know that you don't mix work with romance because if the romance went sour you would still have to work together and that would be too hard. Just let them that you value them as a friend but friendship is all there can be between the two of you.
Unfortunately bite the bullet, you need the job and they will act out if they feel berated or shamed. Unless it's of a sexual nature....you have higher ups for that. Good luck.
no nice way :D confront them
be outright and direct, tell him to go suck and egg
