Have you been threatened over social network comments?

The plight of NSW prison officers is the latest example of employees being threatened with the sack for comments published on social networking sites.

With more and more of us moving private conversations we'd have at the pub or a cafe on to sites such as Facebook and Twitter, the line between "public" and "private" comment is being blurred.

Are employment laws forbidding public comment about our bosses keeping up with changes in technology and the pace with which our lives are moving online?

Has your employer threatened you or commenced disciplinary action over comments you've posted on the web?
