Conflict management dilemma
What does a business owner/manager do? I have a not easily replace star producer that has in essence given up on managing and communicating with a direct. Both claim they've exhausted their desire to make this work between the two of them. This direct is a C+ type performer and the two of them simply cannot seem to get along. Communication between the two of them is mostly short direct conversations and emails. Both are contributing to the problem and I can't lay blame solely at either one. I've spent a ton of time and money working with both on communication skills, conflict management, etc including using outside consultants but seen very little traction for it. So I'm looking for ideas. Do I let both employees go? Do I keep the high-producer but at what ultimate cost-yes she'd be very difficult to replace but is production worth the pain? Do I continue to try and work through the situation? My company is small--there's no HR--I'm the HR dept and I know the buck stops with me but I'm just not sure what that buck is.
