My spouse contacted my employer and tried to get me fired. Is there anything I can do?

I might talk to a family law lawyer as it doesn't sound like your marriage is going to last.  Seriously, have your divorce lawyer tell her divorce lawyer to stop it or pay the consequences in the divorce case.  You'd think your spouse would want you to get a raise, not get fired.  What is your spouse thinking about?  Do you hope the business you are suing goes out of business?  The bank you have your account with closes its doors?
