Don't think for one second you have any choice. You absolutely must fire him. Companies start to suck because of these people. I highly recommend exchanging a generous severance (6-8 weeks) for a signed agreement waiving his right to sue for wrongful termination (and anything else). Every day people sue companies because they know how easy it is to get them to settle. Get him to sign an agreement and pay him for it. Get a lawyer that specializes in labor law (in your state) to draft the template.
