I've been an employer for over 25 years and I'd agree with the general posts of this thread..... FIRE HIM!

Now you did mention that he had a wife and kid, and he's worked for you for two years. So if it were me I'd belly up to some of the responsibility of being a poor employer; afterall, you got a problem with this guy after two years, you must take some of the responsibility, especially if you want piece of mind?

Next time he mouths off, ask him if he's serious about his squak talk or just jaw jacking? Then have a stern talk with him. I've done this and sometimes the employee will start to breakdown, but I can honestly say, it usually doesn't work. End it quick, fire him now.

Get rid of his negative energy, replace him with someone positive.
