It's a big deal in the world of business.
But what's the difference between sharing your opinion and violating your employer's confidentiality? Or that of a co-worker?
Personally, I'm a fan of not burning bridges--especially in business. If I have a gripe with someone, I generally discuss it with him or her. Of course, there are people who choose not to participate in discussion. So yes, I might gripe to someone else. I'd like to believe I choose my confidantes with care.
ClaimsJournal.com had a pretty good article on the subject a few days ago titled Facebook Policies Tricky for Employers, Workers you might find interesting.
