Yes. This is a common issue in business partnerships.
Sometimes the perception is accurate: one partner really is carrying more of the workload or contributing more consistently. Other times, the perception changes when each partner better understands what the other person actually does, how much time it takes, and how important that work is to the business.
Business Partners Counseling helps partners look at the situation more objectively. If the workload is unfair, the work can help partners address what needs to change. We may ask partners to consider a direct fairness question: if the roles were reversed, would you feel the arrangement was fair?
