You’ve probably heard a business owner say, “Partnerships don’t work.” That statement is usually followed by a story of what a former partner did or didn’t do. I have found that no matter what the story, there are two primary things that lead to the death of partnerships. Though rarely noticed early on, these two things start small and over time cause stress to grow into tensions and tensions expand into disputes and disputes evolve into outright conflict. So what are these partnership killers? Unstated expectations and verbal agreements.
