How do I get facebook to stop giving out my employer when I post?

So tere are certain sites as you know that use facebook to facilitate their discussion boards, and people can log in with facebook and post. The probalem is when I post, it shows my employer right next to my name. I don't mind it showing my employer to the people in my friends list, but I do not want that information public (it is hidden from my public profile but for some reason shows up when I post.) God forbid I post something someone does not agree with, and they decide to mess with me by contacting my employer. My position is high-profile in the community. Just submitting my name would be okay though. Can anyone help me with this? I have been all over the privacy settings and I can't seem to stop this from happening.
