Sheryl Sandberg was the one who taught me otherwise. Some years ago, Sheryl started talking to the company about the importance of hard conversations. Whenever weâre feeling tension with our coworkersâthey have a habit that irritates us, we disagree about an important decision, or they do something that seems thoughtlessâshe encouraged us to sit down with the other person and discuss that tension openly. Because if you donât, nothing will get better, and resentment will only grow.
