My Space pages are public documents for anyone to view - that means your HR department needs to review it. It is NOT acceptable to place derogatory remarks regarding your workplace or employees. It was not very smart or professional of whom ever did this. Is the person the remarks are made about aware of them? You, or the employee spoken badly about, can take this to HR and this person can probably be reprimanded for harrassment and possible slander. It does not matter that it did not take place at work.

An employee's comments on his personal page would not "show up" on your company's page. That is not how Myspace works. If you meant other people have gone to his page and found it, you might have to deal with it as any other HR issue. If mentioned to him, he might take the comment down willingly if he knows it hurts your reputation and/or the employee's. Did you have him sign anything against slandering the company when you hired him?

My 2 cents is that a facebook or twitter account would be more valuable to a business than a myspace page.

Correction on my name - apologies!
